83 SC Engine
Top End rebuilt last August
I have recently obtained a
very stong "burble/backfire" when i lift off the gas at moderate speed. I like a small burble but this is beyond that
Recent changes before moving from gentle burble to strong burble
New CDI installed
Backdated Heat
Replaced low oil pressure switch by removing top of CSI, re-install of boot appears to be tight and well fitted
Exhaust has been checked and is tight with new gasket and no discernible leaks. What are other sources that can contribute to this condition?
One suspect is one of my injectors seems a bit loose (the orange insert portion) and i can move it up and down but doesnt pop out..perhaps this needs a new o ring and or sleeve replacement if its resulting in poor gas burn or am I just hoping in vain its something that simple?
Checked all vacuum lines..and found this one loose, I am not even sure what that component is (air restrictor?)...could this be a culprit?
Mixture was not changed from prior to work above
any ideas?
Thank you ALL
Bob
