Okay, so I've had this Raptor sitting on the workbench for a couple years. I bought an old Kart off of a buddy that had stopped racing, and he sold me his kart, motor, and a boat load of tires and wheels for $300. I didn't do anything with it when I got it because I've always played with the clones. I pulled the Raptor off of the bench today to check it out. I pulled the side cover off, and I noticed that the gear that slides over the PTO came off with the side cover. There is a very small piece of keystock that holds it in place. I looked at the cam, and I saw that there was a timing mark on the cam, but it won't line up with the mark on the small gear when I'm at TDC. Is this normal? There is a small mark on the "counterweight" part of the crankshaft as well. Is this supposed to line up with something? Sorry for the bonehead questions. These things are a little different than what I'm used to.
