Product Overview
A handheld blower that starts, then dies when the choke opens—or bogs as soon as the trigger is pulled—often has restricted metering circuits from old fuel. This replacement gives the listed Stihl blower and shredder-vac models a fresh fuel-metering assembly when cleaning no longer holds.
Stihl used several carburetor revisions within these model families. Match the marking on the old carburetor along with the linkage, primer, fuel fittings, and mounting pattern.
This is a high-quality aftermarket replacement or service part and is not manufactured or supplied by the original equipment brand. The names below identify compatible applications only.

Frequently Asked Questions
Q: Why does my Stihl run only on choke? A: A restricted carburetor is common, but cracked fuel lines, a plugged filter, or an intake leak can create the same lean condition.
Q: Does it fit every BG55? A: Carburetor revisions vary, so compare the original C1Q marking and physical layout.
Q: Do I need fresh fuel after installation? A: Yes. Correctly mixed fresh fuel protects the new carburetor and makes diagnosis more reliable.
