This is a project I'm going to start soon. I'm working on an offroad track in my backyard and will need something cool to play with on it.

(And by cool i don't mean a wimpy 1/10 scale like i already have..)
I have a Briggs 2 stroke snowblower engiine of unknown displacement and horsepower (I have the engine numbers, I'll call a lawnmower shop and find out later.). It's 120 volt electric start with recoil backup (both broken! will probably convert to electric start only). Electronic ignition, diaphragm carb (which im not completely sure i rebuilt properly...I had it running for about 30 seconds a while back, before i killed the electric starter pinion gear....)....seems like a good r/c engine to me.
I'm not sure what to use for tires, wheels, or brakes yet. Suggestions would be great. For the brakes I was thinking of something like a small hydraulic disc brakesetup..
I already have some parts and sheet steel to start, so I'll start as soon as I feel like it...
