🔌 Function

The carburettor creates the fuel-and-air mixture required for starting, idle and higher-speed running. Its small pilot and main passages are especially sensitive to stale fuel and contamination.

Common signs of failure:

• Engine will not start after storage

• Engine only runs with choke applied

• Unstable idle or repeated stalling

• Hesitation or weak acceleration

• Lean surging or rich, smoky running

• Fuel leakage or flooding from a sticking float valve

📦 Condition

• Brand new aftermarket replacement part

• New and unused

• Supplied in manufacturer or equivalent protective packaging
