Also in fairness, it was shipped correctly and very quickly... would have been madly happy if it was what I was expecting.

Im not against HD and am very pleased with the quick shipment but did feel shafted enough to comment. So if they ahve been good to you in the past maybe just a quirk... Dont want to slam a guy maiking a living for a quirky error.... but this ad was clearly not anywhere near as descriptive as it should have been and saying move the pinion closer (and RTFM) does not address excessive amp draw with fewer teeth.
