I have a new 3.0 hp high torque starter for a sb chevy that I purchased on ebay and I was wondering if any has had any experienced any problems that I'm coming accross. When I turn the engine over the starter will drag sometimes and other times it will turn right over. The battery hase a full charge and all connectins are good. The battery has 910ca and 720 cca, is it possible the starter has bad spots in the windings ? Let me add the motor is a new rebuild and I have rechecked to make sure I do not have the distribuor out 180. can anyone give me some suggestions ?
