Gas Leaf Blower
BG55 Stihl Leaf blower
Worked without any maintenance or repairs since 2002
Now suddenly it won't go full speed anymore.
Replaced the fuel and air filters and the plug
The parts guy says he hardly ever sells magnetos for this machine
adjusting the high speed mixture screw doesn't help so I returned it to factory setting.
It runs at half speed and then seems to pick up some speed but if the throttle is squeezed to full, it dies. Then I release the throttle, it idles OK, and then the whole sequence is repeated.
Goosing the throttle gets me by.
Sometimes it seems to heal itself at full throttle but the speed isn't there.
Muffler failed, restricting the exhaust?
Governor is intermittent?
What next?

Sounds like you covered most of the important stuff.. Check the lines close for cracks or pinched shut... You may be due for a carb kit as after 7 years, the rubber diaghragms get stiff & won't meter the fuel as they should... Check the lines than look into a carb kit.... Roger

Thanks, guys. . .I hope Stihl doesn't want to many bucks for just the parts. They won't sell me a Factory Manual, parts list or exploded view.
Next time I buy from Sears.

After rereading your post, you may have a blocked spark arrestor, remove the muffler and see if the screen or exhaust port is clogged, if so cleaning it and the exhaust port may solve your problem. Have a good one. Geo
