Kmeyers, Thanks for your input.

I have bought this airplane with everything on it and it had a 7.4 V battery on the ignition with a regulator. That battery was not charging good enough and I replaced it with a 6 V and eliminate the regulator.The plug is japanese. The cowl has sufficient air flow for cooling. I will check and make sure the gas mix is not lean.
By the way, I have been around for 25 years but new on RC universe block.
