This thing is NOT running right.
just would NOT rev, but less stumbling at low and mid revs than before.
WOT is worse.
i like your documentation.
does it actually sound like it is running bad?
i was talking to a guy that weighs about 150# & was getting about that speed with the same specs you have. his sounded ok & he seemed to know how to work on it.
