Has anyone had any experiance with this quad? There is a solonoid on the carb that seems to not work proper. The quad will start and idle fine, soonn as you crack the throttle it dies. If you hold the solenoid about 1/2 way up it will rev on out OK. Soon as you push it back down it dies. Is it some sort of enrichener? It is a 2-stroke motor.Any help would be appreciated! , Darrell
