🔧 Product Description

Aftermarket MerCruiser Rochester 2-barrel carburettor - Replacement Part Number: 1347-818619R02

A marine replacement for the Rochester R2/2GC two-barrel carburettor family used on early MerCruiser inline four-cylinder engines. The service replacement covers the 90HP 96 CID engine and the 120HP 153 CID / 2.5L engine across the listed original carburettor numbers and serial groups. It is not the later Mercarb used on later 120HP and 2.5L production, so the original carburettor number and engine serial must be matched carefully.

⚙️ Key Features

• Rochester-pattern marine 2-barrel carburettor

• Covers selected 90HP and 120HP MerCruiser inline-four engines

• Replaces several early Rochester 2GC carburettor calibrations

🔌 Function

The two-barrel carburettor meters and atomises fuel for the engine's idle, transition and main circuits. Correct calibration is required to maintain smooth starting, stable low-speed operation and adequate mixture under acceleration and load.

Common signs of failure:

• Difficult starting or engine flooding

• Engine stalls when returned to idle

• Flat spot, hesitation or backfire during acceleration

• Lean surging or lack of power under load

• Rich exhaust, plug fouling or excessive fuel consumption

• Fuel leakage from worn bowl, float, needle or gasket components

📦 Condition

• Brand new aftermarket replacement part

• New and unused

• Supplied in manufacturer or equivalent protective packaging
