Hi everyone,
My 1972 Karmann Ghia is having some carb issues as of late and I would like to solve them once and for all.
My car currently has a stock Solex 34 PICT carb, that was "rebuilt" about 6 or so years ago. The rebuild was done by a local carb shop that has been around for decades, and they seemingly knew that carb. The car sits for the entire winter season and is not used frequently, not a good combination for a carb.
Last night on my way home the car simply died out and would not restart for a period of time. I would try to crank it, and no fire at all. After a period of repeated cranking, it did start and I was able to drive it home. My assumption is that something was sucked into the carb, but the filter is spotless?? The car also has times where you give it gas and it hesitates before truly accelerating. It will often stall out after a run on a highway when you get to a red light. In general when the engine is at operating temperature, the idle is poor with rather low RPM's. And finally it is difficult to restart the car once it is warmed up. It usually starts great cold.
So what re my options? Can VOLKZBITZ make my OEM Solex totally new looking and performing again? Are there cases where a Solex is "too far gone"?
My local VW parts store claims my best option is to dump the 34 PICT Solex and run a 31 PICT Brazilian carb with an adapter for my manifold. What are the advantages to the 31?
What does the collective knowledge of the Samba think?
Thanks,
Zack _________________ 1972 Coupe |

What kind of fuel filter?
What do you do to store your car all winter?
Do you drain the fuel tank and run car until it runs out fuel? Use some kind of additive for long term storage in the fuel?
Is the steel fuel line to fuel pump touching hot steel somewhere causing vapor lock? _________________ Joseph

Directly behind the Auto choke is a fitting called the Idle Jet.
Loosen 1/4 of a turn and see if that solves the idling....if so then there is a speck of ? and needs to be cleaned out with Carb Cleaner and air pressure. |

Starts and runs fine... Runs like crap after it at operating temp...Carburetor Icing.
Its your intake manifold, and probably missing other factory installed parts.
Lets see a picture of your engine. |
