Upon removing the K46 from my Ariens model# 936042 (20hp B&S, 42" mower), I discovered that both the brackets were split at the part closest to the rear. Aside from having it welded, is there any other repair that anyone here has done? I certainly can't afford a new mower, and have already...

Very good. Hope I've been of some help.

I have the same model engine. It took me a while to figure it out, as the butterflies were staying open, even when it was cool. I thought I had it set up correctly, but I was wrong. The new carb I got just wouldn't work properly, so I cleaned up the old one inside and out, and reinstalled it. It...

Could it be the wrong carb? If I remember correctly, there were 2 carbs listed, 1 for a manual choke and 1 for the automatic choke.

There's a lever with a spring attached located below the carb. That's the linkage that I had installed incorrectly. There should be 2 holes in the choke lever. I used the wrong one. I had the same symptoms as you did. That's when I finally figured I installed the choke linkage incorrectly. This...

I had a similar issue when I was replacing the carb on my 20hp Briggs and Stratton engine last summer. My issue was the throttle linkage was installed incorrectly at the choke lever. Assuming that your tractor has only a throttle/choke lever, there's 2 holes to attach the throttle cable to. I...

I wonder if it might be easier to just ask for an exchange? Or, just in case, where might I get my hands on some small springs like that?

Thanks. I did make sure that it was listed for that particular engine. And yes, mine is a single cable control.

Well, I checked the float bowl, and from what I can tell everything is there. I got the float bowl attached by putting the o-ring inside the emulsion tube. Went together much easier. However, I did find something missing. The OEM carb has a spring on the choke shaft between the lever and the...

Well, ain't that just peachy. Of all countries, huh? Could that possibly be the country of origin for the carburetor, also?

So this o-ring is a part specifically manufactured for B&S?

Gotcha. I agree, that's a rather stiff rubber o-ring. I have 2 o-ring kits, one metric and one SAE. I couldn't find a similar o-ring in either kit. I was hoping to find one that wasn't as stiff. Apparently these are made special for the manufacturer.

In your experience, was it better to reassemble the carb with the o-ring inside the emulsion tube, or installed on the float bowl?

Thanks. The O-ring was apparently damaged during factory assembly, but it's not too bad. I just can't figure out why it won't fit up in the emulsion tube. If I put it on the metal tower in the float bowl, it won't allow me to assemble the bowl to the carb body, like it's too tight of a fit for...

Another issue I'm having is getting the O-ring on the emulsion tube to seal with the fuel tower on the float bowl. It just seems to large in diameter to fit. Is there something I'm doing wrong?

OK, I guess I may be incorrect. But the original carb had a separate main jet housing. I should take the float bowl off again and compare.

OK, researching the carb parts and I seem to be missing the main jet housing in the new carb. I guess I will be contacting the seller. However, I still don't understand how the horizontal fuel solenoid functions. Still trying to wrap my head around this.

Well, this is depressing. I had disassembled the OEM carb, cleaned it, and reassembled it and installed it back on the engine. It started right up and ran very well. Idled nicely and accelerated well. So, today I am mowing, and it suddenly started surging. I turned off the mower deck, and headed...

Thanks for the replies. The solenoid you're showing is the one that came with the new carb. My question is, how does it function? I can see how the OEM one works, but I can't see how the horizontal solenoid works. There are no other moving parts in the fuel bowl, like there is in the OEM one. Am...

New member here! Having some issues with the B&S Intek 20hp in my Ariens mower. The model number for the engine is 406777, type 0442B1. I had a surging problem, so I purchased a new carb. It appeared to be identical, except for the fuel solenoid. The OEM one was on the bottom of the fuel bowl...
