TB22 TB32EC Carburetor for Troy Bilt TB22 TB21EC TB22EC TB32EC TB42EC TB80EC TB2040XP String Trimmer Weed Eater Murray M2500 M2510 Brush-cutter

I replaced the carburetor on my Bolens BL 100 weed eater. My original had a circular rubber gasket with a loop on the side on the engine side. Orienting the gasket with 4 small holes in it allows the one hole to line up with the passage. The carb and fuel hoses installed easily and the weed eater runs better than when I purchased it 10 years ago.

I used it to rebuild my weed eater that needed the work and it worked great!!

10 minutes to install. They send all the ancillary parts you might need. Take note of the type of gasoline they tell you to use.

Good price easy set up- works well!

Works excellent! Would definitely recommend!

Easy install and is still going strong.

Great kit, but for my application, the spark plug was not the correct one for my TB21EC.

I installed this on a 14 year old Troy-Bilt trimmer, that was functioning at the time. It has become very cranky when trying to start, and finicky to keep running, but it worked. Since I couldn't find a rebuild kit for the old carb, and it doesn't really allow for user servicing, other than spraying it with carb cleaner, I decided a cheap new carb was the best option option I had.Installation is very straight forward and simple. The carburetor looked great and worked fine the first time I cranked it after the install. I let it run for 2 minutes or so, and tested it out; slow throttle up, slow down, rapid throttle up and release, no issues, no stumbling. It was great. It seemed to have taken care of my problem, so I put the trimmer away until I needed it again.The next week I had mowed, and it was time to trim. No luck. I pulled in that blasted thing until I had a blister between my middle and index finger. But hey, it's a string trimmer, they're always hard to crank, right? I left it alone, took a break with a cool beverage for about 15 minutes. Tried again. Nope! After some choice words that may have included some four letter nouns, adjectives and adverbs, I finally put the old carburetor back on.Pulled for another 2-3 minutes, and voila! I had my same old, cranky and finicky trimmer back.I cannot with 100% confidence blame the carburetor. It is possible that it picked up some trash out of my fuel, even though it was fresh. It happens.It may work for others, but it just didn't give me good results.
