🔌 Function

The kit renews the carburettor's float-control, inlet-valve and sealing components. Correct rebuilding restores fuel-bowl level, prevents air and fuel leaks and stabilises the mixture from starting through full-load operation.

Common signs of failure:

• Hard starting or excessive choke/enrichment required

• Rough idle, hunting or repeated low-speed stalling

• Hesitation, flat spots or intake backfire during acceleration

• Fuel leakage, flooding or an incorrect float-bowl level

• Lean surging, reduced power or fuel starvation under load

• Rich running, smoke, spark-plug fouling or excessive fuel consumption

📦 Condition

• Brand new aftermarket replacement part

• New and unused

• Supplied in manufacturer or equivalent protective packaging
