I have the top cylinder not firing at idle and to about 1/2 throttle -- at half to full it runs fine. Turning the low speed screw in/out has no effect on engine. Can I assume the carb only needs cleaning or can there be electrical gremlins causing this? I have cleaned and rebuilt lots of cars and motorcycles - should this carb be any different?
Update: plugs are new and gapless. Top plug was extremely wet when I pulled it but others didn't look much better.......
