Read on for compatibility details, installation pointers, and what’s included so you can confirm fit before ordering.

How do I know this carburetor fits my engine?

Check the original carburetor part number on your engine or the model plate and compare it to 299437 or 297599. This kit lists compatibility with many serials in the 100200, 130200 and 135200 series and several specific model variants—if your engine matches any listed model or part number, the kit is likely compatible.

• Replaces carburetor part numbers: 299437, 297599.
• Designed for engine series: 135200, 130200, 100200 (4-cycle).
• Fits many model codes such as 130201–130237, 130251, 135252, 130292 and more.
• Meant for 2–5 HP engines with a horizontal crankshaft.

What components come in the kit and why they matter?

The package includes the carburetor plus two gaskets, two fuel filters, one spark plug and one valve — everything needed for a basic carburetor replacement and routine tune-up. Including these consumables helps avoid multiple trips to the parts store and ensures a cleaner fuel path and proper sealing at reassembly.

• 1x carburetor ready to install.
• 2x gaskets to ensure proper sealing and prevent air leaks.
• 2x fuel filters to protect the carburetor from debris.
• 1x spark plug and 1x valve for completing a basic engine service.

What should I watch for during installation?

Confirm the mating surfaces and throttle linkages match your original parts, and take care to route fuel lines exactly as before. Small differences in linkage or manifold orientation can prevent correct installation, so compare the new carburetor against the removed unit before tightening fasteners.

• Verify throttle and choke linkages align with the engine control arms.
• Use provided gaskets and torque bolts evenly to avoid air leaks.
• Install fuel filters inline as shown on removed parts to protect the carburetor bowl.
• Test for leaks and proper idle before full operation.

Will this solve running issues like hard starting or poor idle?

A worn or clogged carburetor often causes hard starts, sluggish throttle response and unstable idle; replacing the carburetor and filters can restore proper fuel metering. However, diagnose ignition, fuel delivery, and air leaks as well — not all running problems stem from the carburetor alone.

• Replaces worn metering parts that can cause flooding or fuel starvation.
• New filters reduce contamination-related lean spots.
• Includes a spark plug to eliminate ignition as a quick variable.

Who is this for: This AUTOKAY carburetor kit is intended for small engine owners, lawn and garden equipment technicians, and DIY mechanics who operate 2–5 HP horizontal-crankshaft engines in the listed 100200, 130200 and 135200 series. If you have a matching part number or one of the specified model codes and you need a complete replacement with gaskets and filters included, this kit provides the essential components for a confident repair. Note: always confirm compatibility against your original carburetor and engine plate prior to purchase to avoid installation issues.
