Still no luck after carb cleaning and double checking everything else. I have spent countless hours checking and double checking everything I can think of and still no luck. I'm guessing it has to be a manifold leak at this point as I can't think of anything else. |

Update to my problems carb is icing up and cold to touch also heat risers are cold to touch. Gonna take those of and clean out the carbon. Also ordered a rebuilt German carb with good throttle shaft to hopefully clear up my problems. If those two don't fix it I'm stumped on this thing. |

I would check your float, to make sure it is not taking on fuel and sinking. Submerge the float in water and look for bubbles. Just an idea. |

Got the manifold cleaned out it was clogged. Also changed the carb for a correctly rebuilt unit. Seems to be running good now. Holds an idle now. Just need to adjust the new carb and should be good. Fingers crossed. Thank you for all the help. |

One more thing I experienced that might help you, after I had the throttle shaft rebushed, it cured 90% of problem, then like you I found my heat riser was clogged, cleaned it with drill and old clutch cable, it helped.....finally I adjusted the spring in my fuel pump and brought my pressure down from 7 psi to under 3 psi ( where it should have been all along).....NOW IT RUNS 100% perfect. NO stalling at all.
Hope that helps. _________________ Currently own : 1969 Beetle w/ 1600cc, Single Port, Solex 30 PICT 2, Dist. 113 905 205 T, stock exhaust.

I used the same method on my heat riser as well. Also used a rubber mallet to tap the rougher spots seemed to break up the big chunks. Also let carb cleaner soak for a couple of days. I'm thinking my throttle shaft was also worn. I'll check the fuel pressure as well just to make sure. Thanks for the unfo! |

About the fuel pressure.....I didn't realize ( and didn't read my Bently shop manual carefully enough) that the engine needs less than 3 psi @ 3000rpm, most aftermarket pumps put out about 6-7 psi.....way too much pressure for the float shut off valve, flooding the carb and causing it to occasionally stall. _________________ Currently own : 1969 Beetle w/ 1600cc, Single Port, Solex 30 PICT 2, Dist. 113 905 205 T, stock exhaust.
