Generic Nikki Replacement Carburetor: The Tractor is Running Well Again!
Installed my new carb on a B&S Series 31 engine in a JD LA115. The engine started with the settings from the manufacturer, but needed some fine tuning to run smoothly/ to my liking! It's an older engine from 2009 but it runs very well now with the new carb! Perhaps unlike other buyers, my JD required a new gas tank because it had one of those defective designed tanks that leaked. So my tank and gasoline are fresh and without any debris. I use regular fuel with the standard EPA mix of alcohol, but I have good luck using StaBil as well in my fuel. The carb is doing very well so far for me and I would recommend this seller to those looking for a generic Nikki carb at a good price.

Worked properly for only an hour *Floods engine while off.
I replaced the old carburetor with this particular unit and it started up working great. However an hour later into mowing the lawn the engine started surging and then shutting off. After numerous hours of trying to identify the root cause, including removing and replacing fuel filters and fuel shut off valve, adjusting the carburetor screw etc. I found it was the carburetor. I identified that the carburetors choke would open and close without any resistance and would not spring back. As I was not familiar with carburetors and specifically the choke I had to go back to my old one to see if it would work the same. It turned out to be a cheap spring on the carburetor choke had unwound itself. I ended up having to take everything apart and remove the carburetor to get access to the spring where I used needle nose pliers to rewound the spring and make a slight bend on the end to wrap up and around the black plastic so it will never happen again. Now the final issue I have to address is recalibrating the carburetor as I had adjusted the throttle adjustment screw to the point where it will turn on but not restart. Looking it up online it should take only a quarter to one and a half turns in order to properly calibrate the screw. *Update: Now it is flooding the engine while it's off.
