You guys are great. Thanks for the reply. This is my first nitro car. (I have 8 electric and only got this because it was part of a LOT of vehicles which was hard to pass up).

What do you mean shim the diff correctly?

I'll put a little grease on the bevel gear diff gear and it is good to go then. Awesome.

Hopefully the engine is in good enough shape. I replaced the glow plug and opened the crankcase up to take a look, no rust and while pulling the starter seemed to hold good compression.

Thanks again!
