I jus bought a used savage ss 4.6 with the k4.6 motor with the purple cooling head I can tell the truck was barely used no scratches on bottom truck is really clean but the pull start is stuck I don't know y I hope the motor isn't shot because the motor looks like it was barely run also if so what is another good drop in motor for it another .28 that's reliable and a good motor also they put a reverse module in it and I think maybe they put it in wrong and the spur gear is really tight I have the box it came with it was the ss 4.6 kit
