longtimetiger 1 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,,,,,,,, Share this post Link to post Share on other sites
