Looks like something got stuck in there.----Have an assembly like that with throttle butterfly screw stuck in there.----Just to show folks that simple stuff can make an outboard run awful at idle.----Still run ok at full throttle.

That's what I was thinking too.. never found anything floating around in there.. cylinder walls look amazing not a scratch in them.. pistons look good too
