So tried firing up my 312A after sitting all winter. Dang mice behind battery! Wouldn't crank over very fast. Fired up the 314 no problem. Battery was older in 312 so I just swapped batteries still wouldn't crank fast. Dropped to 10v under load. Pulled starter and cleaned it. brushes don't look bad but it was howling. the bushings were in fact pretty sticky. looks like bronze or oilite bushings.
Do I put a drop of some sort of lube on these bushings when re assembling??
Also bendix sticking really bad i red here that it should have kohler lube but i want to stick back together and try it. so maybe some lithium?
What else could cause slow crank? Thanks.
Should I clean up the stator and file the brushes or not
