I would also further point out...
If you do not fill it as Buzz has pointed out. You can hydrolock your engine if you pump in without
pinching off the line to the engine before filling the tanks..I have a T Filter int the line to the carb
and when filling I pinch the tubing to the carb... Learned the hard way one time..
If it has fuel locked you may also have wasted your glow plug. Check it out of the motor.
