We have just put a new 350 in our 95 Wrangler that is bored 30 over and possibly has a cam in it. We are having a major problem getting it to stay running and think it may be a carburetor problem. We have a reman'd Holley Q-jet carb on it now, with the original fuel pump in the tank, and a Holley blue fuel regulator turning the fuel pressure down to about 8.5 psi and returning excess fuel to the tank. We get the engine to start, it runs for a brief time, and then dies even with the gas pedal pushed to the floor. Does anyone have any suggestions? things to check? how have any of you solved something similar? Thank you in advance.
