I have the NL model. The engine shop says the the Bendix gear is likely missing teeth and the Bendix roll pin is likely sheared and the starter needs to be rebuilt. Problem is that Skytec won’t sell parts so the engine shop can’t rebuild it. I looked on their website and don’t see a link for rebuilding starters, only selling new if they are out of warranty. I think I checked their site a few months ago and thought they offered to rebuild for $350 but I may be dreaming. Any idea if they still rebuild starters or any insight on who does?
