I need some ideas on cooling a pusher type engine. Had one and if it idled any length of time it would overheat. I thought of a bigger head like a heli head but are they available for most engines or are they different. Just don't know but I am sure someone out there has the answer
I have experienced the problem with a number of different engines on a Bob Cat. The lack of pusher prop sizes makes the problem bigger than it should be. Running a smaller pusher prop than tractor seems to help some. Using a larger engine than would normally be necessary seems to help some. Going to the end of the runway and crank and go seems to help, i.e. no taxi time and no run up.
However the engine in pusher configuration often simply runs different in the air and I have not found a solution.
