hmm yeah I thought so.

nah it's not catching on anything outside the gearbox. I was trying for ages tonight and couldn't get it in. it really seems like the hole in the gearbox is like 1/2 a millimeter too small or less. I even took the baseplate (with the shaft still in it) off the rest of the starter to see if the baseplate would mate and it still wouldn't go in. I can probably get a pic or video if it helps??
