My 103 is running great at an idle, but it can't get out of it's own way, really gutless. I've cleaned the carb, carb cleaner and high pressure, confirmed spray through every oraface on the thing. Reassembled and still no change. I did my first ever plug chop, and the ceramic looks pretty white, not tan like it should, also have a little moisture on the mettal rim on the plug body. I've also done a pressure test, 120#, I think that should be ok. Where do I go from here? Also, is there a spring behind the little ball on the main jet? If so that may be my problem because I can't get that to move.
