- So unplug the motor, jack up the engine by the ends so wheels can spin or lay it on its side, jump 9-15v dc power to the motor plug. Also turn it by hand at the flywheel feeling for tiny parts inside clicking or hitting vs smoothness . It may encounter some magnetic pull in spots too, that would be normal. Clicking and sharp hang ups of mechanical issues inside would not be normal. (brush arms)
- to check very well, if you use a power supply and run it for while jacked up that's even better.
- Why-Sometimes brush arms can seem ok, but change shape once things warm up causing mechanical issues inside the can motor. Rare but happens.
