    Hi Chris,
    ok, I had it as* backwards! I think it might be fine, other than the roller going off the end of the cam in the stop position,

    pulled the intake airhorn off to verify the butterfly. and right, in neutral throttle is limited, ok , seems good, thought it would run away for my upcoming first start , Cliff,

    Looks fine to me Cliff. As you found, the throttle is limited in neutral, that is why you need to shift to forward to get full opening of the butterfly.

    Some motors have an adjustable idle stop, at the base of the tower, to prevent the roller from really coming off the cam. Your model does not. the wires there are normal, and the roller will come off the cam at the STOP position.

    Well, the throttle cam pick up adjustment won’t affect the position of the roller on this engine, the cam moves in and out to set the pick up.
    Again, I don’t think those wires are properly routed/clamped into the mag plate, which is why the roller seems to be hitting the wires and perhaps opening the butterfly a bit when the throttle is all the way retarded/in the stop position.

    thanks for the help guys, well I fired it up , runs good , I knew the impeller was toast so don’t cringe to much when you see the water level and no water spray, was very short runs full cool down between and only fuel bowl amount of fuel.

    You need a bigger bucket.
    The cavitation plate should be under water so the pump will prime.
    Motor is sounding good.
