Hello,Oljo here.Trying to get my project boat sea worthyby the 4th but it aint loolking good.Here's the deal.It cranks and runs and revs good sitting in the yard with the water ears,but every time I put it in the creek ,it spits and sputters,doesn't crank good,some times takes off good and sometimes it doesn't.The local mechanic, replaced some reeds and gaskets.It was spitting gas back out of the bottom carb when I carried it to him.I've cleaned and checked the carbs twice.They look good, I can see all 3 spraying when its running. I"m getting fire to all 3 plugs.Anyone had this problem before? Any ideas?
