I just got my Revo 3.3 its got a pull start not ez start but it will not stay running! I will blow in the fuel line to get fuel to the carb then i will pull start it it will fire up then die it seems like its not getting fuel or something i dont know what to do i got new fuel and glow plug still does the same thing. carb adjustments on HSN is 4 1/2 turns from closed and LSN is flush :\ Any ideas????
