Question for you guys I have a 1982 Camaro with a 350 carburated chevy. I have a Holley 4160, towards the end of last summer when I start and drive the car everything is fine. The problem is after I shut the car off it will not start up again untill the car is cooled down for a few hours. Its like the carb gets flooded. What are all of the causes of perculation besides heat. Any help would be greatly appreciated.

Thanks,

Hot fuel pump is cause #1.

Put an extra gasket or 2 between the block-off plate and the block, and between the pump and the plate.

I've even thought about making a block-off plate out of some kind of material besides metal, to get rid of that.

 

I am using an electric fuel pump not mechanical, so I dont think that the block off plate applies, the electric fuel pump is mounted in the rear of the car. I have had the car for 5 years and the problem just started the end of last summer. I have run out of ideas.

Thanks,

The last time I actually used a Holley on a running engine, I had TWO aluminum plate heat shilds between the intake and carb to help that very same problem. Legally, you cannot vent the bowl to atmosphere on any post-1972 street vehicle. Got a spare Rochester?
