Not entirely true, it ran 18mph before the change, 20mph after with 2 people - then after changing the trim angle I went out by myself and hit 22mph, though I'm not sure if that was the trim angle or the extra person less weight.

I didn't think about needing a timing adjustment. I don't see a difference in the steps in the FSM - I can share the google drive link if needed - but perhaps it will need to be set differently within the same bounds.

It is definitely adjusted to idle smooth and slow - you can troll on the damn thing if you wanted to...granted, that doesn't necessarily mean WOT is perfect.
