What's with the World today!!? At one time auto enthusiasts wanted their car to sound like a finely tuned Ferrari or exotic sports car!! Now they put dual exhaust on 4 bangers and mufflers that sound like a pissed off Bee!!:sick: Now this!! :stupid: Automotive evolution my #%&*!! Zedguy

Thanks Everyone!! Will try that!! One thing about living in 'The Great White North'.....you get 6 months to tinker with your Z and 'overthink' lots of problems!! Much appreciated! Zedguy

Yeah!! Done the timing light...plug gaps....vaccum advance. I use the highest octane I can get at the pumps! Thing is, I never had the problem before the rebuild....so something changed?! What would happen if the chain was off by a tooth or two? Zedguy

Hi Z-heads!! Got a pinging problem I hope you can help me with. My Brother-in-law rebuilt my '73 engine a year ago. GREAT....except for the pre-detonation!! It's worse when it's cold....then it's just bad on hard excelleration. It seems to disappear around 3500 RPMs. (Can't quite remember,as it's winter here and the car is in hibernation!!) We've played with the timing and even advancing it doesn't clear it up completely. Could we have gone a tooth or two out when putting on the timing chain? Would that cause this problem? My B-I-L doesn't think he messed that up, but I remember that the new sprockets didn't have the same line-up 'groove' as the original. Any ideas? Thanks, Zedguy
