Bought for Echo TC-2100. The symptoms were that it would fire up & run for about 30 seconds and then die. Took me about an hour to remove and install the parts. I had to trim down one of the tubes to match the old one. Put gas in it, hit the primer bulb a few times, and it started on the first pull. I had to adjust the high jet screw a little as it would rev up and then bog down. After the adjusting it runs like new! On top of it working perfect, I can't believe it was only $12.

Crappy ethanol gas ruined my old carb.
For the price, it's easier to replace it all wth this kit

I ordered this replacement kit yesterday, and received it today, late morning. I have a 20+ year old Mantis tiller. Haven't used it in at least 8 years, and expected carb problems since it is a 2 stroke. I did a complete servicing of everything on the tiller, except the carb and related things. The original had issues with the fuel primer not functioning correctly. Probably a clog in the upper portion, as primer bulb would not fill, but would flood the carb. Anyway, it took about 15 minutes to swap carbs. I am mechanically inclined. Unlike the reviews I read, my rubber plug fit the fuel tank correctly. In addition, there was a 2nd plug packed in the kit. I don't know whether there was a size change over the years, but the kit has been updated. I knew that my spark plug was good, and the engine would fire with the old carb, but only for a second or two. Once I completed the swap, my tiller started on the first pull. I did tweak the adjustments on both high and low slightly, and was still getting a slightly fast idle. The idle adjustment did nothing through its entire range. I used the tiller for about 15 minutes, and the idle did slow down, so was able to make the necessary adjustments then. I continued using the tiller for a few hours off and on, and it would start with one or two pulls, depending on how much it had cooled down. No complaints whatsoever on the product, and the other items in the kit, which I will have for future use if necessary. I have a number of gas powered pieces of equipment, and have learned that it just doesn't pay to fuss around with the old, when a new carb is so cost effective. In the past 2 years I have replaced 3 carbs on different lower use maintenence equipment, all purchased here at Amazon. I've had similar results on all occasions. I love it when things just work! Just guessing, my Echo backpack leaf blower will probably be next in line come fall.

The media could not be loaded. Item arrived a day late. But that's on Amazon not the quality of the carburetor. I have my father's Mantis Tiller that I was able to date to January of 1989. The tiller was sitting for a number of years in the basement with gas. Then sitting outside against the house for a couple years. Rather than trying to clean the carburetor I replaced the fuel tank and bought this Chinese carburetor kit. Took the air shrouds off of the engine cleaned everything out and attached this carburetor and new fuel tank. I then reassembled the air shrouds onto the engine. A couple presses of the primer bulb a little bit of Choke and the thing popped right off. No adjustments needed it idled perfectly and after it warmed up for a couple seconds it went to Full Throttle without bogging.
I highly recommend this carburetor!
Maybe I got lucky, but I would still buy the carburetor adjustment tools just to give the high and low idle screws a little bit of a tweak if needed.
You can see in the video the engine bogs when I go to give it throttle. But that's only because the engine was cold on Startup and I didn't give it enough time to warm up. But you can see it really take off at the end of the videoðŸ‘
Ps, don't mind the bad lawn, we went through a pretty bad drought anything that's green is the weeds🤷"â'‚ï¸

Ease no adjustments needed
