Re: Operational Engine Stand
You might try heating the air that is moving from the fan to 95 degrees. Sort of joking, but my Briggs 3hp 4 stroke off road bike trail riding lost pretty much all its power after riding in that kind of heat after an hour or so. Letting it cool, I started it up and had the power back again. Maybe even with the flywheel fan and shroud with cylinder fins this was too much for it.
