OK so I did some trading and ended up with a Warrior. I was told it needed put back in time and it would run. I went to put it in time and pulled the cam gear cover off and discovered that the gear had a crack in it. I went to pull off the gear and found that the little pin that holds the gear in place broke off in the head. Now here's my questions 1. What all could be damaged being that the pin broke off 2. Could I just weld the bolt and the gear together to fix this I know its probably not a very good idea, but its not in good shape so if I could just get it running and keep it running it'd be good enough for me and keep the cost down as much as possible
