I have a starter that is not engaging-just spinning. I wanted to take the starter off and replace, but one of the bolts is under the flywheel, so I tried to remove the flywheel. I cannot break it loose. First question-there are four phillip head screws that are countersunk and screw through the outside diameter edge of the flywheel and are located 90 degrees from each other. What are these? Do I need to take these out and what do they hold inside? Second question-I inserted a 3/8" rod into a hole located next to one of the above phillip screws, and put a 3' cheater on my ratchet and only succeeded in bending the rod. OK-the rod was a Harbor Freight pry bar that I cut the end off, so probably not the hardest steel, but still, how do I break the flywheel loose? Or is there another way to fix this starter without taking the flywheel off?
