im completely baffeled when i kick my bike rm250 it wont draw the fuel through ive tryed everything tubes are clean floats dont stick absolutly everything the only way i can get it to run and dont laugh is by putting a small amount of fuel in the cylinder head where the sparkplug is as soon as it fires up it pulls the fuel through easy if anyone can help my mysterious problem that would be great
check your slow jets for clogs and when its running check for air leaks by spraying carb cleaner on the carb manifold. might not be getting a rich unf mixture.
