Blower
Stihl BG 55
2-Stroke
The Stihl BG 55 is a 27.2cc 2-stroke handheld blower designed for residential leaf and debris clearing. It is the entry point to Stihl's BG handheld blower range, suited for driveways, patios, and residential lots. The BG 55 runs a Zama carburetor and shares engine architecture with the FS 38/40/45 trimmer family. Common failure modes are fuel line cracking from ethanol exposure and primer bulb deterioration — detectable by fuel leaks or failure to prime. The air filter should be cleaned each season and replaced annually under regular use.

Tune-Up Kit
Common service bundle: spark plug, air filter, fuel filter, carburetor, primer bulb.
Maintenance Interval
Inspect filters and fuel lines each season, replace spark plugs during annual service, and service carb/fuel-system parts when starting or idle symptoms appear.
Before You Buy
- Confirm the full model is Stihl BG 55, not just the family name.
- Check serial number, production date, and regional variant before ordering.
- Match the old OEM number stamped on the removed part when available.
- Compare dimensions, plug gap, thread, fuel line diameter, or chain pitch/gauge where applicable.
Common Mistakes
- Ordering from a family listing without checking the exact sub-model.
- Buying a kit that includes the headline part but wrong gaskets, lines, or bulb size.
- Choosing the wrong carburetor revision when multiple versions were used.
- Installing the correct plug number with the wrong gap.

Replacement Options
Best OEM equivalent
Start with OEM references 0000 400 7000, 4229 120 1800, 0000 350 3502, 4229 120 0606 and match the removed part before choosing a listing.
Common aftermarket option
Cross-check aftermarket listings such as NGK BPMR7A (spark plug), Zama C1Q-S68G (carburetor), Zama 0057003 (primer bulb) against the OEM number and dimensions.
Best for annual tune-up
Bundle spark plug, air filter, fuel filter when servicing the Stihl BG 55 at the start of the season.
Best if replacing fuel system
Compare the fuel filter, carburetor, primer bulb together so line routing, bulb size, filter style, and carburetor connections match.
Best budget kit
Use kit listings only when every included part matches this model page; cheap kits often mix correct headline parts with wrong bulbs, lines, or gaskets.
FAQ
Should I buy OEM or aftermarket parts for the Stihl BG 55? Use OEM when the part controls fuel metering, ignition, or safety. Aftermarket kits can be useful for routine filters, bulbs, plugs, and tune-up bundles when the OEM number and dimensions match.
How do I avoid ordering the wrong carburetor for the BG 55? Match the carburetor number stamped on the removed unit, then compare linkage, choke setup, primer routing, gasket stack, and fuel-inlet direction.
What should I check before replacing fuel-system parts? Photograph the old fuel-line routing, match line diameter and filter style, and compare primer bulb size before buying a kit.
