surging idle - 06/17/15 04:45 PM
I'm open to ideas on this. Car 1969 Charger: Engine: 426 St. Hemi.
Problem: Car is suffering from a surging irratic idle. Car is all original i.e. carbs, distributor etc...
Car will start immediately just doesn't want to idle. Accelerator pump works and as soon as it is off idle it is fine.
What I've done: Car was in-op for about 2 years. I dropped fuel tank and flushed. Blew out fuel line. Replaced all rubber hoses. Took fuel pump apart and completely cleaned and inspected diaphragm. Cleaned Vapor separator. Rebuilt/cleaned both carbs, Soaked rear carb in cleaner over night to clean internal passages. New needle/seat assay's, set float levels etc.. Pulled distributor and installed new points/condensor, lubed shaft etc...
It is difficult for me to keep the car running long enough to put diagnostic equipment on it ( I work alone).
I've sprayed WD40 around the carbs while it's running to see if there is a vacuum leak and I couldn't detect one.
What am I missing?
Thanks
