Backfire on 1988 Marathon...
I did the HEI ignition mod on my 88 Marathon and it runs great now, however there is a backfire sometimes when I let off the throttle. I don't want to blow out my exhaust system, which I just re-did.
Any suggestions? Is it timing? How do I check the timing on the 244cc Robin engine? Thanks, Steve |
