[QUOTE="Tbair, post: 474213, member: 25579"] I have this same motor, so the loose rubber rod is used to lock the motor for reverse. It's supposed to sit inside that little notch, kind of a pain in the arse but doable. Mine I'm running 50:1 and dont hardly have smoke and the temp of the water coming out seems to stay consistent. I am having issues with it cutting out on me even wide open but I think it's my fuel float in the carb being gunked up. They aren't too bad of a motor and can find parts pretty easy if you go through napa marine book. I'm not sure what the troll lever does, I've messed with it in all sorts of rpm ranges and it doesnt seem to make a difference there. Make sure to change gear oil before taking it out and I hope for the best! [/QUOTE]
