Know your part number?

Type the number stamped on your old carb, filter or solenoid. If it's in any card's "Replaces" list, that card stays.

Only know the model?

The engine code on the shroud decides the carb and filters; the deck sticker decides the cables. Here's where to find each one.

Ten-plus seasons at the parts bench

We started out connecting the factories that make small engine parts with the people who actually fix their own machines. More than ten years later, that is still the whole job: the part that fits, at a fair price, with the small pieces already in the bag.

Carburetors, wet-flow tested

Before a Butom carburetor ships, fluid is run through it to check the float, needle and jets under real flow. That's why most arrive ready to bolt on and start, with no screw-turning, and why the gaskets and filters that belong with them come in the same bag.

Filters and service kits

Riding mowers eat filters. Our kits put the air filter, pre-cleaner, oil filter, fuel filter and plugs for one engine in one box, so the whole annual service is one order and one afternoon.

From old part to first pull

  1. 1

    Match the number

    Read the number stamped on your old part, or the model and type code on the engine shroud. Type it into the finder and every card that lists it will stay on screen.

  2. 2

    Swap it in one sitting

    Most of our carbs and kits bolt on with a screwdriver, a 10 mm socket and twenty minutes. Gaskets and small parts come in the bag, so there's no second trip.

  3. 3

    Give it the first pull

    Fresh fuel, choke on, one good pull. Our carburetors are wet-flow tested and factory-tuned, so most engines catch without touching a screw.

What owners are saying

Six notes from people who did the swap themselves.

Mower sat all winter with gas in it and wouldn't even cough. Put the 190cc kit on in about twenty minutes and it started second pull. Filter and plug in the box was a nice touch.
Dale R. · Marietta, GAToro 22" Recycler

Trimmer only ran with the choke half on. New carb, new fuel line, new primer bulb and it idles like it did the year I bought it. Kit had every little piece.
Priya S. · Columbus, OHSTIHL FS55R

Ordered the Kohler 7000 kit instead of chasing five part numbers at the dealer. Everything fit, the oil filter was the right one, done in an afternoon.
Mark T. · Plano, TXCub Cadet XT1-LT46

Blower wouldn't idle after two seasons. Swapped the carb, had to turn the idle screw an eighth of a turn, and now it runs strong. Good value for the whole kit.
Jen W. · Boise, IDECHO PB-413H

I use my washer for work and it was surging bad. This carb bolted right on the studs and it holds steady now at full throttle. Saved me a shop visit.
Luis G. · Tucson, AZGX390 pressure washer

Put it on in October like the page said. First snow came and it fired on the first pull. That's all I wanted.

Butom small engine parts for the machines you already own

Butom makes replacement small engine parts for lawn mowers, lawn tractors, pressure washers, snow blowers, string trimmers, leaf blowers, chainsaws and cut-off saws. Our range is built around the parts that stop a machine most often: the carburetor, the air filter, the fuel filter, the spark plug and the few cables and solenoids that decide whether a mower moves at all.

Every carburetor we sell is wet-flow tested and ships factory-tuned. Most arrive as a kit with the gaskets, fuel line, filter and plug that should be changed at the same time, so a carburetor swap is one job instead of three. You'll find replacements that fit GCV160, GX240, GX270 and GX390 engines, 122000-series engines, Kohler Command and Courage twins, Kawasaki FH and FX engines, and Tecumseh HM snow blower engines.

On the handheld side we match carburetors to the stamp on the old part: Zama C1Q and C1M, Walbro WYA and WYK, and the Ruixing carbs used on newer saws. That covers STIHL FS, BG, MS and TS tools, ECHO SRM and PB tools, Husqvarna trimmers and saws, RedMax blowers, Ryobi 37cc chainsaws and Poulan Pro hedge trimmers.

Fit comes first. Each card lists the models we've matched it to and the part numbers it replaces. Use the finder at the top of this page with your model or part number, and if something doesn't line up, write to us at the counter with a photo of your old part. We've been doing this for more than ten years, and a quick check before you order saves everyone time.
