I just purchased a 71 914 which has been converted from fuel injection to a what I think is an EMPI EPC 32/36 Progressive Carburetor or some other similar carb. The car was running fantastic with no issues at all. Had it out for a drive today, when all of a sudden it started sputtering and wanting to stall. I limped into a parking lot and let it cool down for about 1/2 and hour. I tried to start it, but I had to keep feathering the accelerator to keep it running, at times the revs would shoot up to 4000 rpm without me further depressing the accelerator. I towed the car home and decided I would try and reset the carburator using the carb initial setup recommendations which required me to turn the idle adjustment screw until it contacted the accelerator cam and turned screw about 2 turns. I then bottomed out the air/fuel mix screw and backed it out about 1 1/2 turns. Still the car will not idle. Any thoughts or suggestions? Didn't note any vacuum leaks.

Also check to see what distributor is installed in the engine. If it is a Bosch 009, take it out. The 009 distributor was built for the Type IV engine, but only used on the industrial engine which ran at a steady 3K rpm all the time. The bug guys found it worked great for the Type I motor, so they started using it. But for a 914-4, the advance curve is completely wrong. That will affect the performance severely.
I suggest either a Bosch 050 (rare these days) or the stock distributor for a 74/75 1.8L if you are going to run carbs. Both have an excellent advance curve for a 914-4. |
