Got this 40, was working really good until one day started to backfire out the carberator air intake. Timing check, carb check, everything looks ok, any advise on what could be wrong. Thanks

40c backfire
My 40c did exactly the same thing and what I found was that the pivot pin on points was sticking and some times points wouldnt operate and when they did it would backfire, this was an intermittent problem not continuous

Check valve timing and, as boler76 suggested, check the points for proper operation and also check the distributor bushing for excess wear causing the point gap to be erratic. gregjo1948
