I need help! I tried to start my Tmaxx today but when I hit the start button the electric motor spun and I could hear the gears spinning but the engine wasn't turning over? I took the electric starter motor and gears off and looked in the gearbox and none of the gears looked stripped? I had the glow plug out and the engine turned over by hand but the EZ start system just spun without turnng the engine over. Any help would be appreciated. Thanks!
