1) first make sure you are getting fuel....discontect the fuel line and put it in a bucket/jar ....crank the engine. You should get a cup to a cup and a half in 3 revolutions of the motor.

If you have to...rebuild the carb....get a kit and about 4 cans of Gummout carb spray....tear it down (remember where it all goes) spray heck out of everything.... Even all the little passages....then blow out with compressed air....put it all together
