[QUOTE="kofkorn, post: 416529, member: 7076"] Pull the carb and look at the float. Not sure when the change happened, but they went from a cork float to a plastic one. The old cork floats can sometimes get "Waterlogged' and will sit lower in the fuel than they should. It causes the fuel level to run higher than it should and can cause a rich condition at open throttle. You don't usually notice it at idle because you adjust for it with the low speed needle. I bought a motor that had this condition. It would run poorly and occasionally stall at WOT. I changed out the float and it ran like new. Every time I open an carb and see the cork floats, I replace them with a new plastic one. It's not worth the chance. Good luck! [/QUOTE]
