🔌 Function

The kit restores the fuel-control and sealing components in both the primary and secondary systems. A correctly rebuilt four-barrel carburettor maintains clean idle and cruise operation while supplying the additional mixture required under acceleration and heavy load.

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
