I'm not sure this thing is fukky broken in yet, I'm going to run it more and see what happens. even after going down in jet size plug still looks just a touch rich. How long does it take to fully break in one of theses motors? thanks for all the help. I'm stuborn and wont quit until it runs right!

Don't try to re-jet your carb until you've fully broken in the engine!!! (about 4 gallons!)
It will start running different as it breaks in! (& you'll have to re-jet again)
