Thread: back fireing through the carb

Tweet

I'm glad to see you can take a joke, Bob. Hey Bob, make one more post and you will hit 2000 post count. Or better yet, keep everyone in suspence. No no, I am not telling you to shut up!

Took me a minute; a little under the weather today....funny guys, I'm always entertained here!

Sorry for taking so long to reply. Yeah, its still mest up. Replacing the power valve was my first attempt to fix the problem, but i did not want to go any further until i talked to some of you talented people . I replaced it because a guy at a performance shop around me said it could be the problem. It made the car sound better, but the problem still persisted. It has been around since i bought the car about a year ago. I myself have done nothing else to the engine, but i do not know in full what the guy before me has done. I understand what your saying Typhoon, and it sounds like the next step. I also had a friend recommend the same thing. No i have not done a compression test yet, but can take it into my school shop and check it out. I always assumed that the car would not start if one cylinder was bad though, correct?

By the way the reason it took me so long to respond was because i didnt have time to take advantage of any of your advice due to my transmission some how getting torn up right were it connects to the driveshaft . I didint want to reply before i went through some of the stuff you guys mentioned. I will definetly look at the things everyone suggested, and any more suggestions would be greatly appreciated.

Thanks again

TyphoonZR is on the correct track, a backfire thru the carb is a lean spot.
A larger squirter and a change in the pump cam to a pink one would help.

First thing should be a leak down test on the cylinders, then ohm out the wires, check the timing and the valve adjustment. Doesn't really matter how good or bad the carb tuning is if the ignition, timing, and valve adjustment is off.
