Tech1 please help the races are tonight. I put the regulater on and i set it at 5 1/2 and now i can ajust my air & fuel and also idle i couldnt before thank you. But now it still miss fire also i was told that my distributer might be off a tooth or two i checked its dead on. Also someone told me that it might not be getting enough fuel from the fuel line cause it is teed off to the fuel solinoid i dont see how it would not be getting enough fuel when the nitrous is off. An one more thing someone also told me the timing chain might be streched please help.
