I recently bought a savage 4.6 and im having nothing but trouble with the spur gear. I replaced it probably 5 times already. First i set the slipper spring to the maual of all the way tight and then back it off a half turn. Next i set the gear mesh using the paper method. The problem i have is either the slipper pad melts or burns off or some of the teeth are missing. This is all happens right after i run it the first time when replacing the parts. Now i just ordered a steel robinson racing combo kit (spur and clutch bell) with Mugen clutch shoes and springs. Will this solve my problem? and why am i having bad luck with the plastic gears? I follow all of the instructions. What am i doing wrong?

Thanx
