I still have this engine running a little on the rich side and I will go out and get a APC 15x8 prop tomorrow and try it once again. Ed, I do thank you for your help with this engine and it does start very easy. What RPM readings should I see with the APC 15x8 prop? Will it still be in the 9000 range?
I will be using Omega 10% for the next couple of gallons because I already have it on hand. I will try the 5% if I can find it at my LHS. I think they only have 10% and higher nitro on hand. I don't know if they will order any 5% for just one gallon[]
