2-cycle starts then stalls after 3-5 seconds
Craftsman Leaf Blower. I start it and it runs 3-5 seconds then quits. I have set the idle screw and mix screw per the manual. I have tried new fresh gas, new gas filter, nothing helps. The plug is spot on for gap. If I rapidly move the choke lever back and forth, it will keep running, but when I stop moving it, it stalls. Ideas?
