Butom 503281504 Carburetor with Filters Maintenance Kit for Husqvarna 51 55 Chainsaw WT-170-1 WT-170

You can’t hardly beat these kits for the money. I have a 20 year old Husqvarna 51 and all the parts fit on it fine ...except for the choke did not work quite right.I’m not sure where the fault is ...but the carburetor doesn’t totally mesh with the air cleaner quiet the way the original carburetor did. And the air filter is a little bit “in the way” when you try to pull the choke back and it prevent an easy “lock” to the throttle arm.I had to bend my choke metal arm back at a sharper angle, so I can force the choke to lock open against the throttle on the side of the carburetor. I hope this works for the long-haul. I didn’t send it back ...although I would rather have maybe a different carburetor.The original carburetor choke actuator and throttle arm looks like they are a little further from the air filter and sort of at an angle.On the good side. Runs like a champ! 20 years old.

I really am hesitant to buy after market parts, however, I needed to rebuild the carb on my Rancher 55 and the parts were out of stock. While waiting for them to ship I decided to give this whole kit a shot. I installed it on my saw and after slow turning the engine over a few times to prime the carb it fired on the first full pull with the choke on. After warming it up is did not even need any adjustment. Runs like new. I will still rebuild the other carb but I will run this for now. Well worth the money. I wasn't a fan of the cheap air cleaners but they do work.

Good product. I was skeptical at the price but I installed the card with no problems. The saw needed no adjustments and idled great. I would definitely recommend! Used on a Husqvarna 55 from the 90s.

It is perfect. Everything I needed and 5he price was right. O checked other places on line and local stores. No one could beet the price.

THis is what you need to refresh your saw. I didn't use or need the carburetor.... but everything else worked fine.

Carbeurator works great so far. My Husqvarna 51 was awesome for 20 years, then a fuel starvation problem- would run only for a second or 2. The saw runs great now with only the new carburetor. Fuel mixture and idle speed seemed already adjusted perfect, but readjusted anyways.

I have a Husqvarna 55 Rancher. The gas line is smaller in diameter which does not seal and allows gas into the carburetor air filter area. The fuel filter barb is twice the size as the OEM making it impossible to use. I had to use my original fuel line and fuel filter. Everything else seems to fit ok. I am waiting on a chain and sprocket before trying it out.

Had to use the old gaskets because the new ones did not work, but the Saw started right up once the carburetor was installed.
