Hipa Carburetor Kit for STIHL TS420 TS410 — Direct-Fit Zama Pattern, Wet-Flow Tested with Filters & Spark Plug

This kit includes a direct-fit carburetor engineered to match the Zama C1Q-S118 pattern (STIHL part number 4238 120 0600) along with essential maintenance items—air filter, pre-filter, fuel filter, spark plug, and primer bulb. Each carburetor is wet-flow tested to simulate real engine conditions so you can expect consistent fuel delivery during heavy cutting work. Packaging may vary, and HIPA supplies the full set to save time and reduce parts sourcing when performing a rebuild or roadside repair.

How does this carburetor restore saw performance?

Replacing a worn or leaking carburetor reestablishes the proper air-fuel mixture and steady idle needed for powerful, predictable cutting. The HIPA unit fits the original Zama pattern for direct installation, and wet-flow testing helps ensure each piece pours the expected fuel flow under simulated load.

What comes in the all-in-one kit and why is it useful?

The kit bundles the carburetor with the small consumables typically replaced during a tune-up or rebuild. Having those parts together reduces downtime and ensures the saw runs with fresh air and fuel filtration plus a new ignition component.

• Includes common consumables to simplify installation steps
• Adjustments follow standard L/H/idle screw procedures for two-stroke saws

How does this kit help with long-term saw maintenance?

Replacing the carburetor and related filters prevents common fuel-system failures that cause downtime and costly repairs. Fresh filtration and a new spark plug reduce strain on the engine, helping maintain cutting capacity and extending the intervals between major overhauls.

• New filters block dirt that wears carburetor and engine components
• New spark plug ensures reliable ignition and cleaner combustion
• Primer bulb and matched carburetor reduce starting issues and flooding
