I've about had it with this leaf blower. It's a Stihl, not top o' the line but a good one. I run premium gas using the Stihl label oil at 50:1. Sometimes it runs great, more often not so much. 1 of 2 things happens that I cannot figure. 1) it starts and idles fine but won't take fuel without bogging (fuel filter/air filter OK) 2)starts and runs fine for awhile then starts to bog. Close the throttle the idle stabilizes but won't take fuel and bogs. The shop I bought it from says nothing wrong with it.

WTF? Any ideas guys? I'm ready to go get a cheap corded one,(but I'll need 200 ft of cord)

edit: forgot to mention I don't squat about these type of carbs but ready to hear about jets and such
