have just bought a 250 2 stroke, not sure what model.
It was last used 18 months ago when it ran out of gas and was put into storage.
have not been able to get it to start, battery good, spark good and it still won't fire. after trying start the fuel ends up through the system into the exchust ??
Any one out there that can help !!!!!! ?

 

if its been that long since it ran, you might as well pulll the carb off and start cleaning it.chances are the float os stuck open.
