This is a Good Replacement part.
I hear alot of "I ordered a part from Amazon" horror stories. Do your research before/ when ordering part. Your experience will be just like mine. This was an excellent replacement aftermarket carburetor. Installed it , didn't even have to fumble with adjustments , finished the install , pull compressed the engine and pulled, fired up on first pull and did not sputter, took my machine out and ran it for 2hrs no problem. Great price also!

Wow what a deal with a perfect fit
Just buy the thing! Thinking of ordering a back up because it was so easy to install and cheap. Took 5 min top to install, no tuning or headaches. RUNS FIRST PULL with perfect idle and throttle response!!!!! I spent over 15$ in carb start and cleaner trying to clean out the old carb with no success. Just buy it you'll be much happier than trying to clean out the old one!!

Replacement for discontinued oem.
At the price it was cheaper to replace the entire carb vs. rebuilding the old oem carb on my woodsplitter. Delivered quick and installed fine, no surprises. Operates as it should without issue. Recommended.

Exact fit and no leaks - way to go seller!
The seller’s name is FITBEST, and that name was true to suggested meaning in my case! This carburetor was a nearly identical replacement of the original one provided on my TroyBilt Super Bronco CRT garden tiller (2006 model) with a Tecumseh Engine model OH195EA spec 71263H. The replacement was super easy, just 4 bolts for the carb and two hex head screws+ 1 hex bolt for the air cleaner… the whole replacement took less than 20 minutes. I had to reuse the old gasket that’s between the air cleaner and the carb as this item only supplied the gasket between the cylinder intake manifold and the carb. The tiller went from zero to hero immediately after installing, where it started up on first pull and idled so much more smoothly. Man am I stoked on this new life given to the tiller. No leaks and no fuss— great value at just a few bucks > $10 in this crazy day and age where everything costs an arm and a leg… not this part. For the time saved on cleaning and rebuilding the old carb, this purchase is tops! Kudos FITBEST!
