    :wall The little bugger was running perfect. I was blowing leaves tonight and it just stopped like it ran out of gas. The fuel is fresh, premium, pure gas, no ethanol. I am using a semi synthetic oil. I do not know where to start. I tried a hour ago to restart it after letting it set a couple hours no luck. It started 3rd pull when I started using it today. I was thinking of pulling the fuel filter up from inside the tank as a starting point. I could use some help troubleshooting.

    Is the spark arrestor in the muffler clogged? Mine clogged quickly on mine.

    What is the best way to get to the arrestor. I am looking at it but only from eyeballing from the outside of the guard i without trying to get in to it. How do I get into and remove it?

    On my stihl handheld blower the muffler has a little piece that is threaded in right where the exhaust exits. You should be able to unscrew it and clean it with a torch/lighter or just remove it all together. Most people just take them out.

    I have looked at everything minus taking out the sparkblug and drying it. I noticed gas was coming down a covering the muffler. It still will not start today. It seemed to try but simply wouldnt stay running both chocked, not chocked, throtlle set, not set. I cant get a plug wrench to turn when I get it hooked up. The space is so tight once on there the handle does not leave room to unscrew plug.

    I still have had no luck in starting my BG85. Up to this point I have taken the spark plug out and replaced it. While the plug was out I cranked the blower several times. Checked muffler etc. I installed the plug back and it tried to start but would not keep running. I noticed when I was cranking it that small bits of gas were coming out of and wetting the end of the muffler. What is causing this and what do I do now? This blower was running perfect.:cry:

    I couldnt tell if you had checked for a spark on the plug. Try that?

    Good spark and with plug out. When I put this new plug in it did just start and then just stalled out several times.
