Seems that this year I need to put a little gas into the carb to get the car started initially. I have single Solex carb that no one seems to be able to identify. I'm sure some PO just pulled it off something that was sitting in a junkyard. Once I get car started and it warms up it idles OK but runs rough when you try to drive it. Timing is spot on. Recent (not too many miles ago) tune up with the help of some very knowledgeable 914world brethren. Let’s say it’s a given that there is nothing wrong with the engine. I have an idea of where to go next. I’ve had car for about 7 years. With only what I’ve told you here what’s your opinion?

Agree with Mike. If the carb has never been rebuilt it could very well be that the accelerator pump diaphragm is shot. It will idle on the the gas running through the idle circuits, but when you give it added gas, the additional "shot" of fuel the accel. pump isn't there, or adequate to keep up with the additional air. Might be time for a rebuild? If these symptoms just sort of crept in, that might be a good place to start as the diaphragm slowly decays over time - eventually it just cracks or tears.
Also, FWIW, it might also be a good idea to get rid of that plastic fuel filter. Those things have a notoriously bad reputation for cracking, and in this case, it's going to run fuel down the sides of your engine... right onto the exhaust. |
