This may very well be a stupid question but I'm a goofy guy so here goes. Would a motor running on one cyl. cause an overheating situation? I've done everything I can think of with this motor. I've replaced the impeller the housing looks impecable the thermostat has been replaced I've taken the head off and cleaned all internal ports. I need some help I can't figure it out. Thanks guys. Btw I think one of my new coils aee bad I have a pretty bad miss at idle anything higher it sounds good.
