So an update, I replaced the starter because the gear wasn't popping up to engage the engine.. Now that is fine, it pops up to engage, but it doesn't get beyond the buzzing sound from before. It seems that the starter cant turn "that big fan wheel with the fins on it" on top of the engine.. Even by hand is REALLY hard to turn and occasionally gets hung up. Should it be like this? Should I continue to disassemble the top of the engine? Is there a ball bearing that failed or something?
Let me know plz as I am at a loss.
