You probably just need to change the size of your clutch bell to something smaller.

I'm pretty sure that should work for your Rustler...I dunno much about Rustlers, but that should work. You may want to see what size clutch bell you're running now.

Did you re-adjust the gear lash?

If not, loosen the four engine mount bolts that hold the upper and lower engine mounts together. They should be silver 3mm socket head bolts. (2.5mm hex wrench required) There are two in front of and two behind the engine about a half inch away from it and about three quarter inch apart (DO NOT loosen the identical bolts that hold the engine to the upper mount. Those are the ones right up against the engine and closer together.) and they go through a slotted hole into the lower mount. Loosen those and slide the engine forward a bit. Then get a strip of paper and put it between the clutchbell and spur gear. Now push the engine back toward the rear until the gears mesh with the paper trapped in between. Now tighten the mounting bolts. Pull the paper out and make sure there is a small amount of play between the gears.
If the paper won't pull out or comes out with almost no resistance try again then recheck.
