    What is this engine not doing that you want it to?How is it running bad?How did those screws get out of whack or are they even the source of this delema?There is no element to be concerned with as is the case with most marine equipment.

    Hi C-Raven, it sounds like you have the famous hole in your exhaust pipe, with the cowling on the leaking exhaust is fouling up the fresh air flow to the carb, remove the cowling and ta---da, fresh air engine runs good.Feel free to phone me if you like 514-5272, parts are cheap time wise its about 2 hours for me, cant say for you, but it is an easy fix, if this is the problem.Cheers

    Sorry dont have the number at home here, if your buying the parts from S&G, Bill should be able to get the number of the o-ring for you, being a static seal your old one, maybe okay, I just replace them as routine. Dont forget to make sure the camshaft has not turned & #1 is still TDC when you re-install that belt.P.S. Are you in sales or shipping at your shop?
