Re: Fourstroking @ WOT... help.
first,engine type and size.
if its a new motor,dont expect too much during break-in.
during break in,dont run wide open for too long.
let it warm up a little before driving it too hard.
mine four strokes,much less after rejetting to smaller size.
also by lowering the float slightly,it will run a tad leaner.
i wouldnt fiddle with the jetting until you have a couple tanks of gas run through it.
