I got a chevy 350. Can get it running smooth, instant throttle. Turn the car off go to start it again & it runs rough & sounds like it's flooding with throttle. Mess with distributer again. sound good turn it off turn it back on & it goes back to sounding like crap & does that lowbing. Disconnect the vacuum advance. Adjust the distributer. Runs perfect full responsive throttle. Turn the car off. Start the car 10 seconds later & u have to start the process all over again. Does any one have an idea on what could be the problem.
Reconnected the vacuum advance after adjusting distributer & left it off. Both had the same results.
