try the ghetto way " the Blow Job". pull the fuel line from the exhaust nipple and blow to the end of it thus creating pressure in the tank that pushes fuel to your carb in 0.2 seconds.Place the line back and give it a pull. should start in one!

that's faster that doing 50 pulls and ruin your pull start early.

Don't get over excited with the " the Blow Job" you might flood the motor.
