🔌 Function

The kit renews the float, inlet needle and sealing parts that regulate fuel level and mixture. Replacing these components helps correct flooding, starvation and air leaks in older carburettors.

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
