I'm downloading exploded views as soon as I get access to Better connection don't wanna annoy anybody with what this what's that and the other posts lol. But what is that little gear
That would be the spur gear. It got damaged most likely by the engine moving causing the two gears to clash. Really not a hard job but if you don't have a clue YouTube is your friend.
Well I'm glad I asked I thought it was the spur. And YouTube is a real friend for me in this hobby. YouTube and this site are definitely gonna help master this thing lol
