About this kit

The BG86 shares its engine with the SH86 shredder vac, and both suck in more fine dust than a regular blower. That dust wears the carb's throttle shaft and varnishes the jets. Our replacement follows the Zama C1M-S261B and Stihl 4241 120 0623 pattern and bolts straight on.

The second option adds an HD2 air filter that replaces 4241 140 4400 and 4403. If you run the unit as a vac, take that one; the finer filter protects the new carb from the start.
