FAQ

This kit is designed for a wide range of equipment, including John Deere models LA105, D110, D105, LA115, D100, LA110, LA125, JS40, L1742, 1742HS, and S17. It is also compatible with various engines requiring Briggs & Stratton part 594593.
This unit replaces OEM part number 594593. It also cross-references with a large number of parts, including 591731, 796109, 697203, 792036, 792345, 590400, 593514, 791888, 792358, 793224, 794572, 699937, 697190, 697141, 792171, 791858, 698445, 790418, 594591, 593433, 796078, 699916, 594605, 594601, 591351, and 591951.
You likely need a replacement if your engine is experiencing rough idling, frequent stalling, hard starting, or surging while under load. These issues are often caused by internal clogs or worn-out components within the carburetor that cannot be resolved by simple cleaning.
The most common cause of failure is the use of ethanol-blended fuels. Ethanol attracts moisture and can leave behind gummy deposits or varnish when the equipment sits unused for extended periods. This residue clogs the small internal passages and jets, preventing the engine from receiving the proper air-fuel mixture.
Installation typically involves turning off the fuel supply and draining the tank, removing the air filter housing, disconnecting the fuel lines, and detaching the throttle linkage. Once the old carburetor is removed, install the new unit using the provided gaskets to ensure an airtight seal. Always ensure the fuel lines are secure and free of cracks before restarting the engine.
It is highly recommended to replace the fuel filter and inspect your fuel lines for any signs of dry rot or cracking. Additionally, check the condition of your air filter; if it is dirty or restricted, it will prevent the new carburetor from performing correctly.
