Remove the airbox cover and filter to access the carburetor mounting bolts.
Disconnect the throttle linkage and choke linkage. Take a photo beforehand for reference.
Remove the mounting nuts or bolts securing the old carburetor to the intake manifold and carefully pull it off.
Clean the manifold mounting surface, removing any old gasket material or debris.
Install the new carburetor, ensuring the gasket is properly seated. Re-tighten the mounting nuts evenly.
Reconnect the throttle and choke linkages, followed by the fuel line.

Troubleshooting & FAQ

How do I know if this carburetor will fit my engine?

This carburetor is designed specifically for Tohatsu M5B and Nissan NS5B 5 HP 2-stroke models from the early 2000s. The best way to confirm is to match your existing part number to one of the cross-references listed in the Part Number Matrix, such as 369-03200-2.

What are the signs of a failing carburetor?

Common symptoms include difficulty starting, rough idling, stalling at low speeds, poor acceleration, black smoke from the exhaust (running rich), or fuel leaking from the carburetor body. If you notice these issues, a replacement may be needed.

Is any adjustment needed after installation?

This is a direct-fit carburetor and should work out of the box with factory settings. However, minor idle speed or air/fuel mixture adjustments may be necessary depending on your engine's condition, altitude, and climate.

What is the difference between part numbers 369-03200-2 and 393-03200-2?

Part number 393-03200-2 is often a superseded or alternative part number for 369-03200-2. Both are functionally identical for the specified applications, representing minor production updates or regional differences over time. This aftermarket part replaces both.

Do I need to replace the gasket?

Yes, it is always recommended to use a new gasket when installing a carburetor to ensure a proper air-tight seal with the intake manifold. Leaks can cause poor engine performance.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
