carb question?? blowing out through top.

patrick1989 · May 26th, 2011, 10:44 PM

im not sure but occasionally when i shut my car off it will almost backfire through my carb..... does anyone know why it does that?? i think i noticed it mainly does it when its a hot day or shes running real warm...

Timing maybe??
Had the same issue with my Nova, I would kill the engine and it would stutter then backfire through the carb.

double post

patrick1989 · May 27th, 2011, 02:44 AM

hmmmm... so you fixed your timing and it went away?? or did you do some other things along side fixing the timing??

btw its a 351W stroked to a 408 maybe anyone else has any insight on common problems with these motors doing it with a holley double pump carb??

Bottle Fed GT · May 27th, 2011, 04:06 AM

Yeah after we adjusted the timing it was fine. I had bought a pro billet distributor from msd and i had issues with it from day one. Ended up replacing the whole dizzy and no more issues. That was on my built 358sbc.

no shit! where ya at and what branch?

I had a similar problem caused by a loose rocker arm. if adjusting the timing doesn't help, pull the valve covers and check the rockers.

Moosestang94 · May 27th, 2011, 10:05 PM

that happened to me, it was the timing

Bottle Fed GT · May 28th, 2011, 03:44 AM

I'm in the Army. I'm stationed at Fort Bragg in USASOC. I'm in a Stan but cant get any more specific then that really until I get back.

Your army right? Afghan?

patrick1989 · May 28th, 2011, 11:54 PM

i think my rockers are good i dont have any top end noise but i think its timing cause when i bought the car it was set up for racing they shaved the choke off the carb had huge jets in it and all kinds of crap so im guessing its a fuel and timing problem!

cool guys i appreciate the help!! ill prolly be askin some more!
