Carburetor Tune-Up Kit WT-194

Key specifications

When a chainsaw needs carburettor-related replacement parts, matching the exact saw and part number matters more than choosing a kit by appearance. This WT-194 carburetor tune-up kit is listed for Stihl MS240, MS260, 024, 026, 024AV and 024S chainsaws, with replacement numbers 1121 120 0611 and 11211200611.

The listing also names Walbro WT-194-1, WT-194, WT-403A and WT-403B. Treat those as fitment references to compare with the carburettor already in the saw, rather than assuming every version of a listed chainsaw uses the same part. The product information does not give dimensions or tuning instructions, so the model and number match are the practical checks to make before ordering.

Who it’s for

This kit is aimed at owners or repairers replacing a carburettor and several related service parts together. It may suit a maintenance job where the fuel and oil filters, lines, gaskets or spark plug are also due for attention, rather than someone looking for a carburettor alone.

It’s a fit if your chainsaw’s model and existing carburettor reference match the listed applications and you can handle the installation and setup. A kit with several small parts can be handy at a workbench: you can lay out the replacement carburettor, lines and filters before beginning the repair instead of sourcing each item separately. The listing describes installation as easy, but it does not explain the required adjustment or provide evidence of how the parts perform in use.

It may not be the best choice if your saw has a different carburettor number, or if you need a confirmed match for a specific production version. Without having tested it, the safest buying decision is to compare the old part’s markings and the saw model against the compatibility details, and ask a qualified repairer if you are unsure.

What’s included

The stated contents are one carburettor, one oil filter, one negative pressure pipe, one spark plug, one oil pipe, two gaskets, one fuel pipe and one fuel filter. That gives the kit broader coverage than a carburettor-only replacement, although the listing does not specify dimensions, materials for individual pieces or whether additional installation hardware is supplied. Check that the parts you need are among those listed before relying on this as a complete repair kit.

Buying questions

Which chainsaw models are listed? MS240, MS260, 024, 026, 024AV and 024S are named in the product details. Match your exact model before buying.

What replacement numbers should I compare? The listing gives 1121 120 0611 and 11211200611, plus WT-194-1, WT-194, WT-403A and WT-403B as compatibility references.

Does the kit include filters and lines? Yes. The stated contents include oil and fuel filters, an oil pipe, a fuel pipe and a negative pressure pipe, alongside the carburettor, spark plug and gaskets.

Final verdict

This is a multi-part replacement kit to consider when both the carburettor and some associated service parts are needed, and your saw’s model and carburettor reference align with the listing. If you only need one component, or cannot confirm the part number, a single matched replacement may be a more straightforward purchase. The key trade-off is convenient bundled coverage versus the need to verify fitment carefully, the listing does not establish compatibility beyond the models and references it names.
