I recently installed a new, more powerfull engine in my RS4 racer 2. While doing some testing at the local track, one of the motor mounts came loose, and it backed out just enough to eat up 4-5 teeth on the gear. It was a 44 tooth, and the only thing my LHS had was a 43 tooth. Can I use the the 43 even though it's not listed in the chart? I understand it's supposed to create issues, but will one tooth make that big of a difference?
