    As most of you know I’m learning to be a VW mechanic . On the way home today my car started run bad . I got it home checked fuel pump. Pumped lots of gas .Took top of carb and cleaned . Tightened fuel lines and all other lines . It seem to get worse the longer it runs very poor running .It starts right up appears to be good its like it is either starved for gas or not getting enough gas . The good news I went from not running to very poor running car HELP!!!!!!

    Make sure the coil has the BLACK wire on the coil No. 15 (+) terminal and the green wire to the condenser on the coil terminal No 1 (-). That may be causing the coil to run hot.

    Check the rubber plugs on the carb for cracks. My car acted up a couple times and that solved it. Also there is a disk about the size of a dime on the front of the carb I had mine come loose and the car wouldnt run until I fixed it. Check the jet for a blockage sometimes small rubber particles come off the supply hose after the filter and block the jet.
    I had problems with my car running right on a regular basis until i replaced the vaccume advance on my distributer with an automatic advance.
    hope this helps.

    If the coil is that hot you may need a resistor check with Bubba at this link.

    This is the result of overheating a coil…owner left the key in the on position overnight.

    Replaced coil. Not the problem. Took fuel pump apart. cleaned, new gasgets etc . Carb apart .
    and cleaned. not the problem. I’m wonder is there a filter or screen
    where gas leaves the tank . I took a air hose and blew it in the fuel line towards the tank lots of noise and the car runs like a champ

    Screen or no, a bunch of rust and crap could be blocking the teeny tiny fuel outlet in the tank. That’s what sidelined me in the first couple weeks of ownership. Tank got below half or so, and she’d stall on the way to work.

    Have you looked at the tank vent? If it’s plugged the fuel pump could be lowering pressure in the tank until it equals the suction of the pump. Open the cap the next time you drive the car. If it’s harder to turn and makes a sucking noise you have a plugged vent. Do you have the correct cap? Do you have a non-vented cap on a fuel system that expects one?

    The cap is a boat cap I know because I lost the cap went hunting for a new one and found the exact same one a boat parts store . I drilled a couple of holes in it to vent
