Just picked up a non running LT50 four wheeler for a little of nothing. Looks to be a mid 80's model. Bike turns over with plenty of compression and has good spark. When I was checking it out, I noticed the hose from the oil tank going to the carb is gone. This made me think that maybe someone may have put straight gas in it and tried to start it. I have not messed with 2 stroke bikes much and was wondering what this would do if this happened. I know it will ruin the engine, but will it lock it up, or just ruin some internal parts? Any way to tell if this has happened.
