I
Wish I knew. I always thought it was carb related. The fuel tank is plastic and everytime it would quit running, the carb bowl was always full of black crap. I couldnt take the tank off for cleaning because the thread insert in the tank was stripped and I couldnt get the screw out. Cant buy a new tank either. I blew it out best I could, flushed it with clean gas, blew it out again, installed new fuel line and a large inline filter to catch the crap. I am giving it one last chance and then I'm headed to harbor freight for a new engine. 8hp Predator is $269. I would rather pay that than the $242 dollars for the stator coil kit. I do think if the new coil I ordered dont fix it, I might go ahead and try one of those $17 china carbs. On another note, I have another horse tiller without a engine, (non pto), and I have a new 6hp predator engine, I can put on it. I converted it to a tater digger a few years back, but it wasnt heavy enough to pull the digger so its stripped of parts and just setting in my shed. I have all the parts to turn it back into a tiller.
