I have a Troy Bilt weedeater/power head thing, I don't remember when I bought it, but probably 4 to 5 years ago. Having gummed up a lot of carburetors over the years by leaving fuel in the carb and tank, with this unit I've been religious about emptying the tank at the end of the year and running the engine until it stops, then hanging it with the fuel tank down, so no residual fuel flows into the carb. Also it's only ever had the way-too-expensive pre-mixed gas with no ethanol from Lowes. So I went to start it the other day and it wouldn't start, whereas it always started right up when following the pumping/choking/pulling/throttle instructions printed on the breather cover. I verified the spark plug was clean and it was sparking, so I figured it must be the carburetor. Then I noticed that the machine has the proprietary Troy Bilt "jump starter" system, so I ordered that too-expensive part, hoping to save having to tear the carb down. That came in the mail from Amazon, but even using it with a corded 1350 rpm drill didn't start the machine, even using ether. So I took the carb off, tore it down into its bigger chunks, and soaked them for 20 minutes in a gallon can of carb cleaner I have. Blew it all out with compressed air, re-installed it, hit it with the drill, and........nothing. Didn't even try to catch.So I came to Amazon and looked up that model of Troy Bilt, thinking I'd buy another one so I'd know it would fit the attachments I have (I know they're pretty standard, but there are at least 2 variations of drive splines out there, and that burned me on an edger once ). As I was typing in the model number, Amazon offered "carburetor" after it, so I thought, "Sure, let me check out how expensive a whole new carburetor is." (Because the engine felt and sounded like it had good compression, and it was sparking, so it almost had to be a fuel issue.) I was flabbergasted when I saw how cheap some of these carbs are, so I took a chance for 16.88, got it 2 days later, slapped it on, followed the starting directions, and the machine started up on the 4th pull on choke position 2, just like it was supposed to in "3-5 pulls." I let it run for 30 seconds while holding full throttle, turned off the choke, released the throttle, and it immediately dropped to a nice idle speed and sat there purring like a kitten. I didn't have an attachment on, but blipped the throttle a couple times and it responded immediately and felt powerful. I have no doubt that it's going to run properly, and they even included the adjusting tool in case it needs a little bit of tweaking.IF YOUR POWER HEAD/WEEDEATER DOESN'T START, BUY ONE OF THESE CHEAP CHINESE CARBURETORS! I've messed with engines all my life, and I really didn't think this was going to work (because I'd cleaned out the old carb), but it absolutely did. A 10-minute swapout and I'm back in business. The next time a small engine gives me trouble the first thing I'm going to do is come to Amazon and buy a cheap carburetor for it.

Great product and worked out of box.

It took about 30 minutes to swap the carb on my 8 year old Troy-Built R22 curved shaft trimmer. The motor was slowly getting rougher and dying with throttle application. Adjustments helped for a while but not a cure. This new carb fit right on and the trimmer runs like new! What a good deal. Note: Trim the new fuel lines at an angle to help them more easily slip into the fuel tank.

The media could not be loaded.

Carburetor was easy to install. No instructions but there are enough YouTube videos out there. Removing the old carburetor and putting this one on took 5 minutes. Okay maybe 10 minutes.Once the carburetor was installed it needed to be primed a little bit longer than normal but what's the engine started, it didn't need any adjusting. I'm using a Troy-Bilt TB32EC. I was trying to adjust the old carburetor but no matter what I did the unit would bog down as soon as I added power. This new carburetor was set perfectly and the string trimmer runs like brand new. For $14 it's not even worth taking the old carburetor apart and cleaning it. This literally took no time to change, doesn't take any extra mechanical skills and worked absolutely perfectly. I've used the unit three or four times since installing it and it's still running great.

Worked fine

My neighbor's 15 year old weed whacker wouldn't start and after a quickie carb job I determined that the old carb body was smoked - too much ethanol gas, too much water. A quick search indicated this was a direct bolt on fit and it installed in just a few minutes. These low cost aftermarket carbs are hit or miss (usually miss) but this one in particular works like a charm, and even came with a replacement weighted in-tank filter.

tres bon produit et fonctinne super bien
