Lots of good information listed but my experience with about 4 of the ST3000/3250 size engines is overheating which leads to lose of power and if you do not land soon the engine stops. I cannot get it to run rich enough to prevent the above weather the engine is cowled or not. I realize that I have not listed any where near all the info that would be needed to diagnose a problem but has anyone experienced any situations similar or have suggestions of possible causes or solutions. Thanks
