hoppedupandcutdown Posted July 2, 2017 Report Share Posted July 2, 2017 Check the flywheel key. Maybe even reeds. Quote Link to comment Share on other sites More sharing options...

sleeper06 Posted July 2, 2017 Report Share Posted July 2, 2017 Could have developed an air leak. Pressure test before you tear your hair out 1 Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted July 2, 2017 Report Share Posted July 2, 2017 You mentioned spark plugs made a negative difference. Were they solid tip or thread on tip? Quote Link to comment Share on other sites More sharing options...
registered user Posted July 2, 2017 Report Share Posted July 2, 2017 flywheel key would affect both cylinders. check it if you want but I don't believe its your problem with backfiring and a dead cylinder I would probly first look at cdi and coil. if your using any Chinese ign parts I would suspect those very first thing Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted July 2, 2017 Report Share Posted July 2, 2017 Have you got to put a compression gauge on it to make sure it's not fried in one cylinder? Checked for air leaks? Quote Link to comment Share on other sites More sharing options...
