The carburetor is compatible with Zama C1Q-W38, C1Q-W40A, and C1Q-W31B models . Replaces OEM part numbers 545081848, 545081850, 545130001, 545006060, and 545006062.

A: Comprehensive kits typically include the carburetor, air filter, fuel filter, fuel lines, primer bulbs, gaskets, and spark plug. Some kits also include a tuning tool, extra gaskets, and additional primer bulbs. This provides all components needed for a full fuel and ignition system service in one package.
Q: What are the symptoms that indicate the carburetor needs replacing?
A: Common symptoms include the engine being hard to start, stalling after starting, running rough at idle, hesitation on acceleration, or loss of power.
