I have a 1995 RM 125 with a 1994 engine, and it will hardly ever start, and when it does, i ride it for literally 10 seconds and then it dies, but before it dies it bogs down and I have to pull the clutch in for it not to stall, but even after i do, it stalls anyways, and then it wont re-start. I think it may have something to do with the gas flow, considering it bogs down when I attempt to ride it. I read somewhere that the 2 screws on the Carb adjust the air and the fuel, but I dont know how much both of these screws should be turned- so if anyone could tell me how much/little to turn them that would be great. Thanks. Also i cant tell the 2 screws apart.
