Hi,

I have a Force 26 engine that was running o.k and lately started to act up. It is difficult to start and when it starts, it will not go to WOT but will quit. I use 15% nitro fuel with a MCOY 9 plug. I have also tried other plugs without much success. My high speed needle is open 3 turns. Does anybody have an idea of what I can do? Also, What is the factory setting for the low speed needle?

Thanks,

Le fou
