Tapa Recoil Starter Carburetor Kit for Honda GX340 GX390 GX420

In this review of the Tapa Recoil Starter Carburetor Kit, the bottom line is simple: it is a comprehensive, cost-effective tune-up kit for owners of small engines based on the Honda GX340, GX390 and GX420 family. The kit includes a complete carburetor assembly, recoil starter, ignition coil, air filter, spark plug, gaskets and mounting hardware, so it is aimed at DIY mechanics and equipment owners who want a single-purchase rebuild that restores starting and running reliability. For anyone needing a full service kit rather than piecemeal parts, this Tapa kit stands out for coverage and value.

Key Features

• Complete tune-up coverage: The kit bundles carburetor, recoil starter, air filter, ignition coil and spark plug so most maintenance tasks for GX340/GX390 style engines can be done from one box.
• Adjustable carburetor: The included adjustable carb with sediment bowl lets a user fine tune fuel delivery to match engine condition and application.
• Strong recoil assembly: The recoil starter uses a robust pull cord, pulley and spring designed to replace worn original Honda-type starters for reliable starting.
• Extensive gasket and mounting set: Gaskets, insulator and mounting bolts and dowel pins are supplied to simplify installation of the carb, muffler and valve cover without running back to the parts store.
• Broad fit and replacement parts: The kit is made to replace common GX340/GX390 11-16 hp carburetor and starter part numbers and fits many applications such as pressure washers, log splitters and water pumps.

Who It's For

This kit is well suited to owners of 337-420cc small engines based on Honda GX340, GX390 and GX420 designs who need a full rebuild or tune-up package. It is ideal for people who maintain pressure washers, compressors, water pumps, log splitters or other outdoor power equipment and prefer a single kit that contains most common consumables and hardware.

Those who should look elsewhere are users who only need one specific OEM part or who require factory-authentic branded components for warranty reasons; this aftermarket kit is intended as a practical service solution rather than an OEM-only replacement.
