Thanks Atul and Rcpattern,

I´m waiting more than 3 hours and the engine not start. Just in another day the engine work and just one fly and the problem starts. Do you know if the Cool Power 30/24 have a excess of oil for this engine? If the excess of oil make the diaphragm in the regulator stops and only after hours when the oilflow andthe engine work again? Its proceed?
Is normal use in this engine a injection syringe to force the fuel to engine?
