It’s been awhile so I thought I’d update my thread here. I see that the photobucket fiasco has robbed this site of many pictures as well.
Zella will be getting a new carb once she is nestled into her new home. I’m in process of building a 48×64 shop right now. If interested you can follow along on the Garage Journal forum at the link below.

I spent quite a bit of time attempting to get her to idle correctly. I felt as though she was tuned very well driving around, but she would not idle whatsoever even after the new manifold. After speaking with the previous owner he told me that he’s always had the same problem, no matter how many mechanics he had look at it. So I’m going to get a new carb and go from there.

1969 VW 1500cc drivetrainEdsnova, there are 2 more longer tabs that I’ll weld to each end. These tabs will extend up into the bucket and meet with the side plates and secure the bar to the bucket with bolts. That way I can remove it if needed. My coworker dropped his bucket off to me today so tomorrow I’ll get his fitted and finished. More pics to come for you guys.
These are made from 3/8″x5″ wide stock that I cut down with a plasma cutter. A 6″ abrasive wheel cleans up the angled edges fairly well.
scubasteve, I’ve seen a few pics of what you describe. Love looking at those old war machines. Thanks for the compliments, I may not be good at everything I try, but I do enjoy it all.
I guess I’ll have to throw up a few pics of the hydraulic post hole digger I’m making as well. It will attach to my tractor via 3-point hitch. 😀

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainNew intake manifold is in. Hopefully this weekend I’ll have time to throw it on.
Meanwhile, been working on getting a quote for a Morton building. Looking at a 54x60x14 building.
Also, took some time to build a few toothbars for tractor buckets. One for me, one for a guy I work with.

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainWill do, thanks! I started with a junk one to begin with. This being a maintenance item, it doesn’t look as though it’s ever been done.
Once a year should do the trick I think.

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainAdopt me!
Haha I’m assuming you’re saying that based on my proposed shop size? My wife is an amazing woman. We’ve been talking about sizes and she just keeps telling me to build what I want the first time. 😀
This could get expensive!
Anywho, I ordered a new intake manifold. I wanted to go ahead and replace the rest of the exhaust but it’s still solid so I’m holding off on that. Should be back together this time next week.

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainI can only laugh at what I found. She was icing, no doubt about it.
First off, the flanges were nearly welded shut by the folks who built the exhaust. Not only that, but the thru-holes from the heat riser pipes to the exhaust headers off cylinders 2 and 4 were anything but correct. I’m guessing once they welded the flange pipes to the headers, they used a torch to blow the thru-holes in the head pipes. Well the holes were about 3/16″. One side had 2 holes, the other had one.
Drilled the flanges to 7/16″ and the thru-holes to match on both sides.
Then I blew air through the heat riser pipes that then join the intake manifold via a cast aluminum housing. Atleast I tried. No air was making it. Started tapping on the heat riser pipes and chunks and chunks and more chunks began coming out. Finally got the riser pipes clear to where they meet the cast aluminum housing and air began to blow out between the riser pipes and the intake manifold. The riser pipes had rusted out so I went ahead and cut the riser pipe off with a cutoff wheel just to see what was going on. By this time, I had knocked quite a bit of stuff loose.
Yep, plugged of solid. So at this point, I’ve beaten the cast aluminum piece to the point where it cracked. It didn’t matter really, I had decided to replace it anyways. Like my dad has told me for years, “Ahh, the joys of motoring!”
On a lighter note, my wife and I have been talking, and we’ve decided it’s time to look about building a shop. Most likely won’t build one until next year, but atleast I have plenty of time to decide on the size I want. I’m thinking a 50×60 with 12′ ceilings. That should be plenty big for Zella and friends.

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainI pulled the carb back apart to double check I had all the passages clean, which I did.
She fired back up, the choke plate all the way open once it warmed up then, then she quit idling. The intake tube under the carb was ice cold. Felt the heat riser pipes coming from cylinders 2 and 4 and they are barely warm where they attach to the exhaust flanges.
I’ll be heading back out to the garage shortly to tear the flanges apart and see what I can come up with.

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainI threatened Stirling with spinach for dinner if he didn’t tell me how to fix it. Man that kid can keep a secret! 😀
Vacuum leaks are next on my list after confirming the correct jets are in it. I know the previous owner said he’s had it worked on a few times and it’s apparent.
The throttle shaft is definitely loose fitting in the carb body which is a known issue for these. If they’re as bad as I think they are I’ll bore the holes and press some bushings in there.
It acts lean when revving and returning to idle, atleast it is based on my knowledge with tuning carbs on small engines. It revs fine but takes 3-5 seconds to return to what I consider its point of idle. The carb tuning guides talk about observing engine speed changes during adjustment of the volume screw but I observe none. A few 1500cc engine running videos online show them acting the same so I’m not entirely sure if it’s just the nature of these engines.
Here’s a quote I found from vw-resource.com regarding the heat risers on the exhaust…
Someone wrote to say that his ’73 Super with a 1600cc engine runs just fine around town, fine getting on the highway, fine on the highway, but as soon as I slow down, i.e., get off the interstate, engage the clutch, she stalls out on me. I usually pop the clutch and get her running again. Most of the time though, she won’t even idle after I get off the highway. It usually takes a few minutes for her to be back to normal. I’ve tried adjusting the carburetor (Solex 34PICT), and adjusting the timing (009 distributor), to no avail. Am I just not adjusting it correctly?
Rob responded – Sounds like manifold icing. Even in warm weather, if the riser tubes that heat the manifold are blocked, you’ll get ice in the inlet, due to venturi effect (the mixture is forced into a smaller tube, it moves faster and cools the inlet). You really need to take off you muffler, and try to clean out the riser tubes.
Easy to check: when it acts like it wants to stall, feel the inlet under the carb. If its frosty, or really cold, you have blocked risers. (This is only really relevant to the Bug that has run on the highway for a while.)
Also, check to make sure the heat risers are hot to the touch (careful – the right one may be VERY hot). If they are not, you may have an aftermarket muffler or header with heat riser flanges that are not drilled through into the header/muffler pipe. See our discussion of this situation above.

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrain–Your idle shut-off valve is good? Good!
I had originally overlooked this, but my 30 PICT 2 does NOT have an idle shut off valve. It has a fixed jet in it.
From everything I have read, the West German carb I have came with one but it was common to replace them with a fixed jet when they failed. So now I need to verify I have the correct size installed and start from there.

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainThank you. I’m hoping he takes to wrenching like I did growing up.
My receiver is a Sherwood 8910 at 60 watts per channel. Provides me with some great tunes when I’m alone in the garage. 😀
I’m not entirely sure what’s going on with the idle circuit. She just doesn’t want to stay idling when on the road. When in the garage, she stays running but when braking on the road she shuts off.
I’ve attempted to tune it according to a few different guides for the 30 PICT 2 carbs but just can’t seem to get her dialed in where I want her. Maybe tomorrow will offer a fresh start. I dropped the front pressure to 18 and the rears to 28 and she handles much better now. Put quite a few back-road miles on her today.

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainMost of the parts came in so yesterday was spent installing the new distributor, plugs, wires, fuel lines, tuning the carb, etc…
Stirling approves and was wearing his car-tuning clothes.
Working on getting it in. After setting the engine to TDC-compression (verified by pulling the valve cover on the right bank and finding TDC after the intake valve closed on cylinder 1), I noticed the notch in the distributor shaft was 90 degrees off where the old distributor was. The notch in the old one was pointing at cylinder 1 plug wire on the cap whereas the new one was pointing at cylinder 2 plug wire on the cap. Attempts to time the distributor with a timing light on cylinder 1 plug wire yielded after-firing through the exhaust. This verified my initial thought that I should rotate the plug wires counter-clockwise around the cap. Timing off the “new” cylinder 1 plug wire resulted in an engine that jumped right to life. Set timing at 7.5 degrees BTDC and she was idling, albeit a bit roughly.
This plastic float hold down piece was missing when I tore it apart and I think it was contributing to my issues with the float not seating, flooding the crankcase with fuel. I purchased a Radke carb rebuild kit and was very happy with the quality. The carb to intake manifold gasket was punched a bit small on the inner hole and after a bit of trimming I was a bit more satisfied.
Fresh out of the carb dip tank.
After letting the engine warm up, the rough idle turned into a non-existent idle. I tweaked a bit on the carb and was able to get her to idle, but not quite like I want yet. She drives completely different now with new tires and an engine that pulls very well into 4th gear. I was easily able to maintain 55 mph on my road and Zella felt pretty stable, maybe a bit too rough, but I’m still at 35psi on the tires after I put them on and didn’t realize that until after I put her up for the night.
Yesterday was a huge step forward and I feel extremely happy with my progress. Someone else was as well.

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainI found a station about 24 miles from me that has non-ethanol fuel. Guess this is a good reason to build a fuel tank to keep 20 gallons or so on hand.
{-Zella-}
1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainAnother round of parts should start trickling in here soon…
Rebuild kit for my 30 PICT 2, PerTronix Flame-Thrower Vacuum Advance distributor, plugs and wires, new vacuum and fuel hoses, fuel filter and fuel shutoff valve.
I figured a Seafoam treatment of the fuel during the off-months is best and dealing with fuel in the oil from an occasional stuck float will be remedied with a fuel shutoff valve. Was going to do a 12v electric shutoff valve but a manual one will do me fine.
I was working on peeling the carpet back but decided to leave it alone for the year since the weather will be breaking soon. It desperately needs replaced but some things will just have to wait.
Zella should be road ready within a few weeks!

1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainI thought it to be a type in the title of his ad but he repeats it in the description. Either way, nice car. I love the color scheme. I think Zella needs a partner. If I only had the space…
{-Zella-}
1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainGot that right. I can’t wait for nice weather.
{-Zella-}
1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainThank you! If you find all that time, I’ll take some! 🙂
{-Zella-}
1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainThank you both! The weather was not cooperative this week or else I would have taken Zella for a spin.
I was, on the other hand, able to get a bunch of other work finished in the garage all while having my 8-month old job boss looking on.
{-Zella-}
1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainNo I never did get around to getting it copied. I need to though.
Thanks, I finally got the intake welded up. Needs polished but it fits okay. By the time I got it finished I started getting the hang of TIG welding again. It’ll do for now but I’m going to build another one that extends down into the passenger side of the fake gas tank. One of these days.
My son son is getting really big really fast. Started crawling on the day he turned 8 months.
I thought I knew love when I married my wife, but that was only the start.
Anywho, here’s the intake.
{-Zella-}
1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainHaha those who are close to me know I’d rather take the hard road and build it myself than buying something off the shelf. Something I’ve inherited from both sides of my family, no doubt. It doesn’t hurt that I’ve been blessed with a great career that allows me to enjoy multiple hobbies.
The stainless was actually left over from a previous project that I finished. I bought a used 400 gallon stainless sprayer tank off a farmer and built a stainless water circulation manifold that hangs off the side of it to circulate hot water through water to air heat exchangers in my HVAC ducting to heat my house. I burn wood for heat and my outdoor wood burner only had 400 gallons of hot water storage and I effectively doubled that and can store a lot of BTU’s in all that water.
The stainless material was a great excuse to buy a TIG welder and teach myself something I’ve wanted to learn for a few years now. I never really caught on to aluminum TIG, but stainless is nice to work with. One of these days I’ll break the ice on aluminum again and build a tank for Zella.
{-Zella-}
1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainYep that would definitely work! I’ve spent enough time fitting up my pieces, I’m not turning back now. 😉
One more piece to cut tonight on the band-saw and I’ll be ready for tacking for fitment then weld it solid. Overkill, but a one-off piece of overkill.
It may not happen this year, but when I replace the wiring harness most of the wires will be hidden and out of sight.
{-Zella-}
1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainI cut some pie cuts out of some 2″ schedule 10 stainless pipe so they’re 15 degrees total for each piece. This requires 6 pieces per 90* total angle. I laid it out today and I can get it to fit but the engine lid is just barely making contact with it where it comes off the carb so I’m going to be doing some 20 and 30 degree pie cuts to try to limit the height of the piece for maximum clearance. I’ll try to get some pics up as I go.
If all goes well, next week I’ll have it all welded up and that will be checked off my list.
{-Zella-}
1984 BCW Model 52 kit on a
1969 VW 1500cc drivetrainBut realistically, how many of us could still make moves like that?
I turned 29 today, I’m still a youngster 😉
