Briggs & Stratton 594593 Carburetor

Fit perfect on John Deere LA105 with the single cylinder 19.5hp Briggs & Stratton engine. Fired right up after installation and mower now runs smooth again. I previously wasted my time starting with the ultra cheap chinese replacement carb. The Mower symptoms were as if the choke was on and was misfiring as though spark plug was fouled, also would not idle. I chased the ghost by checking valve clearances, push rods, rocker arms, head gasket, spark plug, fuel pump, replaced anti backfire solenoid two different times, new fuel filter, cleaned factory carb twice, replaced solenoid again, swapped carbs multiple times. Bottom line, had I merely not cheaped out and spent the ~$100 and replace the factory Nikki junk carb with this Briggs & Stratton carb, I would have saved a lot of time and aggravation. So, writing all this in hopes to save someone else from going through the same issues. Also, I had no problems with the choke function on this Briggs carb. I did not have to modify anything.

This Carburetor from Briggs & Stratton works perfectly. I had purchased a knock-off carburetor, and I had nothing but problems with it. My advice is to buy an original Briggs & Stratton carburetor!

Just get this if you need a new carb. Do not go with a Chinese option, I had to learn the hard way. After using this for a year now in my LA105 I have not had a single issue.

walbro carb 19.5 b$s intek , poulan pro riding mower, installed no mods necessary, replaced failed nikki carb , purring like a kitten better performance by far. !

The used open box carburetor came packaged in a plastic bag inside of a plastic shipping envelope. As a result, the choke assembly was shattered during shipping rendering the carburetor useless. I happened to have an old carburetor that I was able to salvage and retrofit a replacement assembly from. Otherwise, the product worked and was cheaper than new in the box.

This carb smoothed my 21 hp Briggs right out.. I messed around with the cheap knock offs and had nothing but issues. Now my mower is smooth and runs like new. It even idles down like it’s supposed to. Well worth the money for an OEM part. You won’t be sorry after you try it. I was amazed.

I should write a book. My Briggs&Stratton Engine ran terribly from when it was brand new. I tried the following: 1. knock-off chinese carburetor rebuild kit. Ran Crummy. 2. I tried American rebuild kit. Ran Crummy. 3. I tried Chinese knockoff entire carburetor. Ran crummy 4. I tried Walbro Style knockoff. Ran Crummy. 5. I bought the Briggs & Stratton OEM Genuine Carburetor...................I now cut the grass with a Rolls Royce Lawn Mower. That was the missing link. It's just hard to believe the same engine runs sooooo much differently. ie PERFECT. I was never able to use this mower for about 9 years because it was hard to start, had so much exhaust fumes to make it uncomfortable. I even began seriously to doubt my own mechanics skills. But with this carburetor, it runs effortlessly, and beautifully. Remember, each time I did a rebuild or carb replacement that entailed a LOT OF EFFORT to pull everything off of the engine in order to get to the carburetor. The mower is a Husqvarna R 120S. Why did B&S not put this carburetor on it in the first place instead of the Nikki ( crummy ) carburetor. Hope this helps someone who is going through this.

Tried one of the cheap knock off carbs on a 17.5 HP B&S. Engine barely ran - surged - No power - wouldn’t drive. Bought this one - engine ran great - was mowing 40 min after it arrived
