Just bought an 86 Camaro IROC Z28 with a 400 small block, racing cam, and a 750 holly carb stock tran and clutch as far as I know. It starts off a jump but it takes a few attempts. At first we noticed fuel leaking from the top bolt of the fuel bowl closest to the fire wall because the thread is stripped. But it still started. We tightened it with gasket sealer and then fuel shot out the intake like a geyser and over flowed past the air filter. On top of that the wiring to the alternator is getting high resistance so it's not charging the battery which is why it needs jumped. Any suggestions would be greatly appreciated.

 

welcome to the forum. i moved your thread to the 3rd generation section for you. the section you posted in is for 5th generation questions/issues. sounds like a fuel pump or carb problem to me. guys here should be able to help. enjoy.

 

The "bolts" on top of the bowls are the float height adjusters. Gas shouldn't be anywhere near that high, your float levels may be set too high.
