I installed a 4" fan blade on the engine. It is over driven at 2 to 1 and as it does help with the cooling it is not as much as I had hoped for.

I was concerned that the long o-ring belt would whip around when running but that is not a problem.

I also installed a couple of handles.

I believe the engine would benefit from larger flywheels and heavier intake springs as there is some blow back into the carb. I would like to see the rpm dropped by at least half as it is running around 1500 rpms now. That would help greatly with the cooling also but for now I will take a time out.
Thanks for following along and making comments and likes.
