7.5 running poorly Carg settings???????????

[damon]

I have a 32" tunnel hull with a 7.5 K&B outboard that ran great the first time out this year. Since then I can not get it to run correct. A neighbor gave me some 10% nitro fuel that I've been running, I don't think this is what was in the first time out. I believe it's the carb but i'm not sure which way to go. It runs great out of the water which I don't do for more than a couple seconds. When it hits the water it'll run but only on very short burst, I have to feather the throttle to keep it running but when it finally loads up it'll get up and go but only for a few feet then I have the feather it again. Which way should I go?

I think you are running too lean still. Did you read...

Make sure you have the exhaust pressure to the tank. But the running fine outside the water really sounds like it's too lean to run in the water.
