Answer check the sensor in the dist assesmbly .. make sure the accell pump is working...to check it hook up the hose and crank it over for a few secounds... that should let the fuel pressure to build up... now with the engine off remove the flame aresster, look in the carb and have some one pump the throttle you should see a squirt down the carb throat..
