My starter went south yesterday (makes spinning noise but won't engage the flywheel). What should I expect to pay to have it rebuilt (already pulled it out) and what is the cost of a new (or rebuilt one)? I see on eBay that I can just buy the gear drive nose piece. Would it be worth it to buy that and replace it myself (how do I know if that is the problem)? Thanks for any help! My 67 M715 is now stuck outside in the yard (it has been garaged since the FD bought it in 1985 and I got in 2005) and I don't want the elements to start working their evilness on it.
