[QUOTE="wmk0002, post: 416352, member: 13975"] Have you tried it on the water yet? Pretty much any 2 stroke ran in a barrel will smoke exponentially more than one on the lake. Then there is the possibility the motor hasn't been used much recently and has lots of old carbon it's burning off. I'd take it to the lake and run it wide open for a good amount of time using 50:1 and see how much it smokes when you then bring it back down to idle or midrange speed speed. I bet it won't be noticeable and if it were me I'd run the richer fuel/oil mixture to err on the safe side. [/QUOTE]
