Welcome new/old to iboats!

I think I would buy into a miss adjusted carb first. This engine has a high speed needle that may be run out way to far. But you will not really know until you can run it and see what the engine runs like at wide open throttle.

When the needle is open to far, it lets' to much fuel into the combustion chamber. Not all of it will get burnt and you get that sheen on the water. The engine probably will not have much power on top end either because of the rich mixture.

Probably should have gotten a ride in it first to see first hand what it does.
