longtimetiger Posted August 24, 2013 Report Share Posted August 24, 2013 Daft thing to suggest, but have you got the ignition timed on the right stroke - on compression ? Good spark, fuel, no starting only back-firing suggests you're timed up on the exhaust stroke, 180 degrees out. Just a thought,,,,,,,, Quote Link to comment Share on other sites More sharing options...
