Kizut carburetor for Stihl BG55 BG85 SH55 SH85 – replacement for Zama C1Q-S68 / OEM 4229 120 0606, direct-fit fuel delivery

Kizut BG55 carburetor is a direct replacement for many Stihl BG55/BG85/SH55/SH85 leaf blower models, designed to restore fuel delivery and reliable starting.

This aftermarket carburetor is built to match the mounting points and fuel connections of the original Zama C1Q-S68 series and select C1Q-S55 variants used on small Stihl two-stroke blowers. Whether you need a direct swap because your old carb is leaking, clogged, or out of adjustment, this unit provides the correct fitment for numerous BG and SH series models when part numbers align. Before ordering, confirm your engine model and the existing carburetor part number to ensure compatibility.

Which Stihl models does this Kizut carburetor fit?

This carburetor is compatible with a broad list of Stihl handheld blower models that share the same mounting pattern and fuel line layout. It replaces Zama part numbers in the C1Q-S68 family and the OEM #4229 120 0606. Confirm visual match of throttle/linkage and fuel port orientation to avoid ordering the wrong variant.

• Fits: BG55, BG85, BG45, BG65, BG46 variants and many SH55/SH85 models
• Replaces: Zama C1Q-S68 (and C1Q-S68G/D/E) and OEM 4229 120 0606
• Check differences between C1Q-S55 and C1Q-S68—throttle linkage differs
• Verify by matching mounting holes, throttle arm, and fuel line positions

How do I know this is the correct replacement for my blower?

Identify the carburetor by comparing the part number on your old unit and inspecting the throttle linkage and fuel fittings. Many Stihl variants look similar, so matching the physical layout prevents incorrect purchases. If your current carb has a C1Q-S68 marking or the OEM number 42291200606, this Kizut BG55 unit is the intended swap.

• Look for Zama markings like C1Q-S68 on the housing
• Compare throttle arm position and fuel line ports before buying
• Verify compatibility with your engine model in the owner’s manual
• Contact seller with photos if uncertain about fitment

What should I expect during installation and tuning?

Installation follows the standard removal of the old carburetor and transferring throttle linkage and gaskets to the new unit. After mounting, basic idle and mixture adjustments may be required for smooth operation, because aftermarket carbs sometimes need minor tuning to account for altitude and fuel type. Use small, incremental turns on adjustment screws and refer to the blower’s service manual for factory baseline settings.

• Transfer gaskets and linkage from the old carb where applicable
• Start with factory screw settings, then fine-tune idle and mixture
• Check for fuel leaks and secure hose clamps after installation
• If unsure, have a small-engine technician perform the tune

Are there important differences between similar carburetor part numbers?

Yes—C1Q-S55 and C1Q-S68 look similar but differ in throttle linkage and fuel line routing, which affects direct interchangeability. Ordering the wrong variant can result in mismatched throttle geometry or hoses that don’t reach. Always compare the physical characteristics, not just model names, to ensure a correct fit.

• C1Q-S68 variants correspond with OEM #4229 120 0606 in many cases
• C1Q-S55 may require different linkage orientation—do not assume fit
• Inspect fuel inlet/outlet positions before purchase
• Photograph your current carb and compare to product images if unsure
