When to Replace

• Engine fails to start or requires excessive priming/pulls to ignite.
• Engine surges (hunts for RPM) or stumbles under electrical load.
• Fuel is leaking from the carburetor bowl or overflow tube.
• The generator only runs when the choke is partially or fully engaged.
• Visible varnish or heavy gumming inside the fuel bowl from stagnant, stale fuel.
• Spark plug shows heavy carbon fouling or the air filter is saturated with oil/debris.

Installation Tips

• Drain the fuel tank and carburetor float bowl completely before beginning the replacement.
• Take a photograph of the throttle linkage and spring configuration to ensure correct reassembly.
• Remove old gasket material from the engine intake manifold to ensure a vacuum-tight seal with the new gaskets.
• Ensure the air filter housing is free of debris before installing the new foam element.
• Hand-thread the new spark plug to avoid cross-threading, then tighten to the manufacturer's torque specification.
• Use fresh, stabilized fuel (87 octane or higher) to prevent immediate clogging of the new carburetor jets.
