I had a scat doghouse shroud on my oxyboxer with a type 4 oil cooler. I used it to get better clearance for my dual weber ict carbs. it didn’t cool nearly as well as the fi shroud does with just the type 1 oil cooler. it didn’t have the venturi ring on it though and it also had an aftermarket fan in it.   I think the VW guys are right though, t…[Read more]

I need to adjust both my doors – they are sagging and rubbing the bottom door jamb. Unfortunately, the stainless steel screws have fused over the years and I’ve been unable to loosen them. I kicking this can down the road, since I’m facing the very real possibility of having to drill them out to fix it…

I hope people are using Never Seize when…[Read more]

FYI – You can buy a venturi ring and install it on earlier shrouds. I’m running a Scat doghouse shroud (with heater tubes), the larger VW fan, and installed one of those venturi rings on it. It provides a similar function as a carb velocity stack – it smoothes out the airflow at higher RPMs since the air no longer has to travel around a 90 degree…[Read more]

I already had a large fan (aftermarket) and a doghouse shroud, so this was an upgrade to the FI shroud and a volkswagen  fan.

Eddy, that addition of larger fan and the vortex ring on the new shroud likely increased your cooling air flow at least 20%, perhaps as much as 25%. Good move, IMO!

Have fun.  It may be (with a little luck) that only the throttle shaft needs replacing and the bushings are ok.  That’s relatively simple and straightforward.

There are instructions for setting the float height on-line.  It…[Read more]

Only challenge encountered returning from Carlisle was that GPS could not find Canada. Changed setting to Buffalo NY and as soon as I crossed the border it reset Strange

Will be removing carb to check on float which I assume as some adjustment screw to change float level. How can one repair the throttle shaft bushings? I don’t have…[Read more]

The original builder did a poor job of fitting the splash pan around the engine tin. I used the curvature of tin as a mold and added a number of layers of fibreglass to reduce the size of the gap. I then purchased the following from CIP1 which I was able to slide between the tin and splash pan without removing the engine as they recommend…[Read more]

Thanks Kent, good idea.

WILCO!!

I installed a fan housing and fan from a 1975 fuel injected engine today. this housing has the “vortex ring” or what ever they call it!  It is also made a little different so doesn’t require the “hoover bit”.   I highly recommend it! appears to have reduced my temps by at least 10 degrees. even at 75 miles per hour I didn’t go over 210 degrees an…[Read more]

Roy, I suggest you fold your strip of inner tube to make two layers or flaps. Put the fold to the outside, and fasten it to the body. Then take a dull screwdriver, paint stirrer,  putty knife or similar and carefully work the bottom flap down underneath the engine tin. Leave the top flap laying on top of the engine tin. This will give you…[Read more]

If you can get heat risers working on your intake, I suggest you do so before you start trying to tune your carb. If you are running an aftermarket exhaust, make sure it has the holes drilled out to allow that heat flow to occur – most do, but I’ve seen some that don’t, requiring me to drill/ream the hole out.

I like velocity stacks, they contain…[Read more]

If you are leaking fuel, it sounds more like your float is set too high or is leaking by or you have a leaking gasket.  The reason I say this is because the throttle shaft and bushings are normally under vacuum and would only leak air into the manifold which would cause a lean mixture.  Squirt some oil on the throttle shaft and see if it changes i…[Read more]

The reason that we had such a Rube Goldberg fix on the linkage of Jack’s Holley BugSpray was because of interference with the alternator.  I had no problems at all with my “old school” generator.

Hey Ed,

The issue with the throttle cable has to do with the route the cable has to take to reach the BugSpray Carb.  We had to chop down the intake manifold to get it to fit under the engine cover on the BCW — which forced us to re-route the throttle cable into the left side of the engine compartment and then take a sharp bend to reach the…[Read more]

Remember when tires had inner tubes?   Well, I have a large one on hand and am planning cutting it up and seeing about making a better seal in/for Migi.  Before the show in Virginia Beach.
