Hello all. I have a force .28 motor that came out of my wife's CRT and when the out door temps get too hot (over 100), the engine doesn't want to run. When the temps are around 85-95, the motor runs great. Would putting a colder plug in the motor help? Please help!

McCoy MC-9 IMO its the best cold plug made!!!!!!! i ran them in the same motor and never had any plug problems....

Unfortunately, the manual for the motor tells you NOT to use a MC-59 as it has no idler bar and the fact that I tried it and it didn't work. I'm going to get the picco plug that came with it and see if that helps. They recommend a medium plug for this engine.
