My beloved Stihl BG85C about 12 years old is not starting. I have replaced and checked the coil and spark plug. Replaced carb with Amazon $13.00 carb. Drained and replaced gas. Using starting fluid. No start, not even a cough. Sounds as if it has compression, but have not looked at piston. Any ideas would be much appreciated.

Thanks
Scott

Have you checked the screen in the muffler?

Well, if it is plugged, it will run rich for a while. So do not use the choke for the first pulls, it may be flooded too.

Thanks Fish. I have not. I will take a look and report back.
So on this one, and I am figuring you must know this already with your credentials, the spark arrestor is simply a screen that slides into the muffler. Pulled it out, and it was clean. In inspecting this blower I realized that I had it serviced by my local Stihl dealer last year. So arrestor screen was new along with air filter and spark plug.

Any other ideas would be appreciate. Tempted by the new Stihl blower vacuum 56C, but if I can get my old blower going. I will stick with this. I maybe use these for 3 hours a year, so very light use.

Thanks, I will try again without choke. I have been using the choke initially both with and without starting fluid.

Yeah, if it is flooded, you ought to drain all of the fuel, and pull start it with the trigger wide open, until you get a hit. Otherwise, you should remove the muffler and take a peek at the piston. Also check the flywheel key. But try the flooding thing first.

Fish, a little embarrassed, but it was very flooded. wet muffler, plug seat and all. Cleared it out and running like a champ. I really appreciate the help. Good luck.
