Runs great
My mower would only run if started with brake clean. I took the original carb off, cleaned everything and same result. Bought this carb, 15 minute install and mower fired on the first pull. Impressed for under $20.

Top notch carb and kit.
Great kit. Hose a little snug - includes enough for crankcase vent hose replacement also. Hose clamps tight fit well plated. Filter leak free. Nice to include the governor springs and an extra spring. Springs are well formed and same diameter wire as OEM - Donโt see these in a kit often. Intake prong gasket is exact fit and god material and elasticity. Air cleaner gasket is well stamped nice clean holes and contour. Fits perfect and hold in housing tight for easy installation. Carb is well made, very nice clean casting - has no casting numbers. Carb jet inserts are well machined. Throttle and choke shafts good fit. Carb is identical to OEM, no adjustment screws on body. And the best part, works perfect and leak free. And includes everything you need. Considering you would spend 60% plus for just the bowl gasket needle and seat a great value with the extra parts and a complete carb. The only thing that would have been nice is a bowl drain addition to displace water in the fuel easily when it happens.

Mower Runs Like New on the First Pull!
Installation for my Craftsman Mower Model Number 917.374541 (Engine is Briggs and Stratton 128T02-1270-B1). The price and convenience is right for me compared to trying to deep clean or rebuild the original. It was a very simple job that took 20 minutes including replacing Air Filter and some cleaning of the area. The kit came with Gasket and O-Ring which we used. It also came with replacement fuel line, clamps, springs, and fuel filter which we did not need. It appeared that the Springs would fit if needed; it is nice to have those in case the originals break. Tools used: Open Ended wrenches (including a small 1/4 inch one) and small sockets. You could possibly do it using Pliers with patience and care not to round-off the bolt heads. But at least sockets are needed for the bolts the secure the Carb to the Engine. Do pay careful attention to the Throttle and Choke Spring linkages: They are not hard to get off/on but they need care. I took a few photos of the original Carb setup first in case I went all dear-in-the-headlights during reassembly. The mower started literally on the first pull (though we also replaced the Spark Plug and used fresh gas). If this Carb fails within the next few years, I will update this review. But we are very happy at this point! Good luck! UPDATE 6 JUN 2021: Two things: This is the second season with the first installed replacement Carb and it is still running like new (installed in June 2020). I use fuel stabilizer over the winter and fresh gas now in the spring. And based on my luck the first time, I just bought another one. This time for my Dad's Craftsman Mower 917.370770 (Engine is Briggs and Stratton 126T05-1070-B1). The kit came with a fuel filter (which I didn't use) and some fuel line (which I did use because the original on this second mower was cracked and rotting). The only reason I didn't add in the filter was because there are only 2 hose clamps with the kit (and the new tube OD is smaller than the original, so I couldn't reuse those with the new tubing) and those 2 supplied went to the fuel tank end and the Carb end. The only thing that was a little off is that the spring for the governor linkage that is supplied with the kit seems just a little stiffer, and that is causing the mower to run faster than it used to. I will probably be able to adjust-in the speed; and if not I will reinstall the original spring. If need be, I would buy this a 3d time without hesitation!

Works with caveats
This review is a mixed bag, while the carburetor ultimately worked there are a few caveats. The carburetor body itself is of decent quality, everything moved freely without binding and the mounting face were smooth and flush. The Choke plate on the new one is solid rather than having the cutout like on the original. I suggest looking closely at yours and if its different remove the old one and install it in the new one, otherwise it will flood and fail to start after sitting for a bit. The included springs don't seem as robust as the originals, and only time will tell as to the quality. The included included gasket and o-ring seem sufficient, the included fuel filter are notorious for failing but at the time of this writing it's working as intended. The replacement fuel line is garbage. If you current fuel line is in good shape you'll be far better off leaving it on for the replacement. Overall it was a decent deal as long as you know there may be some modifications to suit your particular needs.

Cheap carb. Great fit. Runs perfectly.
I installed this on a Craftsman model 128M05-F4 (Briggs & Stratton engine). It fit perfectly. Included are two of each of the 2 springs required which is great - should you lose control stretching that small one it will shoot so far you likely won't find it but this kit gives you another chance! Once installed and gassed up the auto choke worked perfectly and the carb is delivering the perfect fuel/air mix for the engine. Longevity will be interesting to observe but at this price level, if I get a season or 2 out of it I will certainly buy another one and do it again!

Before buying carburetor make sure you need side carburetor and if you do it does work great
Let me start off by saying this carburetor worked exactly how it should I have no complaints but for people who have lawn mowers with these carburetors and your your lawn mower won't stay running it wants to bog down and die before you waste your money on this carburetor there is a tiny little spring that goes from your air vein where it attaches to the top of your carburetor over to a little metal hook it's a really tiny spring and it's really easy to lose so make sure you have that spring before you waste money on a carburetor if you have that spring and you truly need a carburetor it's worth the money

Screw thread
The screw thread seems not matching with my original screws. Had a yard time to tighten the screws. Had to buy another one, a different one.

Comes with all the parts needed. I would suggest reinstalling the old gaskets if not damage
Replaced the old one and work really well with no issue. Comes with all the parts needed. I would suggest reinstalling the old gaskets if they are still in a good shape. Highly recommended.

Easier to replace the carp than maintain it at this price.
Does what it should, same proformance of the OEM carb. hoses, clamps not as good but are certainly better than the ones you are changing if you're doing a carb replacement. Easy all in one kit. If you want to do a full maintnance grab one with the air filter. Take pictures of the original set-up before and as you dismantle. will help greatly as you install the new carb.

Saved me $$
My mower of 13 years had issues , I brought it into a small engine shop to get it checked out. Told me the Carb was shot and needed a new one. Asked 225 for the repair. EEEK. Got this for a great price and saved mucho $$$$ Works great now. No issues so far, I will be happy if it last even 5 years. Only reason it gave it 4 stars is that the plastic parts and super flimsy so careful but hey for this price not complaining.
