Timing Question - Help !!!!
Can anyone tell me what might cause my 79 (350) to start quickly when cold, but do nothing but crank once it's warmed up?
I have about 500 miles on a fresh rebuild and I'm going insane trying to figure this one out. I let it get cold and it starts. Run it for ten minutes and try to start it - No Go... It cranks and after a few tries I smell gas, but it doesn't seem to be getting a spark.
Any thoughts??? Marc

Most likely it is flooding. Look closely down into the carb for any gas leakage. Try holding the pedal at full throttle to start.
Had the same problem with my carb when I got the car. It was running way too rich for whatever reason and I had much difficulty starting the car with a hot engine. After cleaning the carb, replacing all the seals, and tuning it up, the car started running much better.

Re: Timing Question - Help !!!!
Thanks for the feedback. You were right!!! Since I don't know the Qjet too well and just couldn't figure this out, I took it to a local hotrod shop. There apparently was a spring missing off my choke and it would stick either open or closed. So, once the engine got hot, I was effectively trying to start the car with the choke on. Works great now - Thank you...

Go get LARS paper in the CORVETTEFAQ section on setting up the Q-Jets or search the posts on adjusting the chokes. Chances are it is working but out of whack.
