car sputtering after ignition off
Ok, i'm not a mechanic and this is probably a stupid question, but after working on the timing the last couple of nights, the car has started sputtering/spitting, trying to run after i turn the ignition off. I think it has something to do with the timing but I would appreciate any thoughts/comments. I've done pretty much everything myself on this car, and have been trying to set the timing, but think i might drive the car to a local mechanic. Help would be appreciated.
Thanks - Gary

That's a common problem (run-on) if the idle speed is set too high, or the timing is too "retarded" which requires the throttle plates to be opened excessively to provide the desired idle speed.
What's your idle timing and speed?

After I installed my ZZ4 into my 68, I had some engine running issues that I thought were related to timing. I took the car to a garage operated by an old guy who been in business for probably 40 years. My car was a classical case of an early 70's pre-smog car needing a tune-up. He didn't really charge me that much. When I drove the car away from his garage, it was a different car.....a noticeable increase in power.
For the older non computer controlled engines...breaker points, HEI distributor, you need ..sometimes.. a specialist to set the engine up for max power.
