It's my fault but it's infuriating none the less. Never drained the fuel or added stabilizer to my 2 stroke Stihl tiller. Went to start it today and the primer bulb never fills with fuel. I tried in vain to start it. Sputtered once then that was that. Think I flooded it. Two hours later same shit, sputtered once. Now the primer bulb stays down most of the time. When it does pop up and I press it there is minimum fuel visible in the bulb and it bubbles in the fuel tank with every press. Suggestions?
