on Stihl BG 55, BG 65, BG 85, SH 55, SH 85 Blower
Blower seems to blow about 50% speed
Had the same problem after about 10 hours of use. The exhaust port screen is likely clogged with carbon. Remove the exhaust port on the front of the muffler and start the blower. If it revs to full throttle, then the ports the problem. Clean the port with carburetor cleaner and reinstall. If there’s to much build up, get a replacement port from your Stihl dealership.
