why would he do that?

Yes I know, I've helped on quite a few meth cars.

In one post he even mentioned a "brown" buildup overnight.

Corrosive and Hydroscopic, Methanol with cause rust. Flush the carbs and cylinders out on race gas, same thing upon firing the motor up. On a cool morning the latent heat of methanol won't let the engine warm up. rings/pistons never expand and seal.

Yeah.......he put nitro in the tank.
