Dar the reason for the new plug was I could not remember when I changed it before hitting the dirt and being put on the shelf. It was time any way.

Dauntae, have you check the valve clearance? If they are a little to much it will mess with the idle. Also check the one way valve. I did find that it did not like certain plugs. Mine would not run with an O.S. #8 plug. It did run well on an Enya #3 and a Fox miracle plug with Power Master YS 20-20 fuel 13X5 or a 13X6 prop.
