Ok, I have a new 150 engine, just about broken in, the thing is awesome except when I go inverted it cuts back like it wants to die, (1/4 to 1/3 throttle) I can give it full throttle and keep it running but that is not something I want to or can do with all moves. It also looses RPMs on vertical for a moment.
I have checked the gas tank, twice. don't get no better. 50oz, large clunks, copper tube in tank to keep clunks from going forward, vent line open and unobstructed.
I have richened the low and high needles a 1/4 turn, no help there either.
Very annoying, Any help would be appreciated.
Thanks,
Wayne
