i was outing together the mt for budy ,installing the steal gears,went together just fine.gears wear smoth,untill i instaled the two moter mounts ,i could berly turn the gears at all,so i took them out.and fore some reason they got loose again .so i filed them down till the just slid under motor .and gears are loose again.it was stisting gear plate so c & D GEARS were binding together.any one have that problem.
