I've searched the forum, the internet but can't seem to find the reason my exhaust is popping on deceleration, except for the obvious...the sportexhaust.
Lately, thanks to this forum, I transformed from 'not touching the car' to 'i'm a mecanic.' (Avoid my wife, she is not happy with that.) What started with starting trouble, was fixed by changing the carb. As always, once I get going there's no stopping me so I basicly did everything I was afraid off before. Checked and set valve clearance, set timing (static with bulb, advanced with super fancy timing light), checked condensor, changed and learned how to read spark plugs, set breaker point gap, checked for air leaks carb etc etc.
The engine is running perfect. Starting on first try, after 20 seconds of choke I get it to idle steady with choke off, even at very low rpm if I want. The one thing that I can't get rid off is the popping (and sometimes a small bang) when letting of the gas. It never happens on idle or acceleration. This was driving me nuts because all seem to be ok. Than I started thinking.....could it be that the sport exhaust causes this and should be seen as a feature? (not one i like.)
From the moment I got it (6 months ago) i noticed some popping on decel from the back but being a nood, I never investigated it. Lately I discovered that I could manually rev the car from the engine compartment (duhhhh) so I can clearly hear it coming from the exhaust.
Am I searching for a problem that doesn't exist?
- Imb 28 carb
- 650 cc
- wasted spark
