I just bought the thing in October and am already having trouble. Sometimes it will run perfectly fine a then other times it will start and run but when I give it gas it will stall out after a few seconds, If I choke it when it is dying I can kkeep it running but when I give it gas again it will die again. I have checked the spark arrester, fue, fuel filter, air filter, all seem to be ok, not sure whart else to do. I am ready to go to the store and get a new arrester , fuel and air filter and if that doesn't do it buy an Shindy backpack and move on. Any suggestions??
