Cheap Chinses Carb

[sgkent]

I do not know what carb that is but I am a layman at this like you, although good at it from restoring many engines and items over the years. The photos of the B&S 594593 are slightly different than your photo, and I cannot find a photo online of an original B&S 794572. The only original one I could find is still in the box and the guy posted just a photo of the sealed box and not what is inside. I agree that it is frustrating but that is par for the course on old equipment. I recently went thru it with a carb I bought from a quite respectible local dealer. Iy looked about the same, came in a B&S box with a slightly different number, but it did not work right. The old stock one I found on fleabay was same as the original and the engine now runs like new. Since I opened and used it I could not take the one back to the dealer. They have been good to me over the years, and I did not want to trouble them with a return.

I might add. Some carb seats require a special tool to remove and insert without damaging the surrounding area. The tool is not expensive but it adds time to the repair. If something else is causing the leak like the solenoid, then that could make the repair more expensive than buying a replacement. There is a fellow on ebay with a sealed box B&S 794572. Maybe if you want it he can open the box and take some photos to be sure it matches. I think it was $111 or something like that. https://www.ebay.com/itm/165496979929?epid=2099154563&hash=item26886381d9:g:4soAAOSwjsxii-VZ

If he does indeed have a walbro carb, and the walbro/Briggs part number is correct, he will not have a seat to replace, since the needle is Viton tipped.

Scrub. I believe you are thinking about the Nikki that replaced the Walbro but if reaseach is correct the current supersede is a Ruixing carburetor.

But the Walbro did indeed had replaceable inlet needle seat. See item 106.

Hmm, the Needle part number that was marked walbro...... EDIT, Oh, i see now, it has a replaceable brass seat, i was referring to a viton/rubber seat.

I took the bowl off and this is what I found.

The needle tip was breaking off and before I put it back together it broke off.
It looks exactly like the needle that was suggested right?

 

[StarTech]

Yes.. And would be the cause of the fuel leakage.

Ok, so a new needle, I probably need a bowel gasket, a new float wouldn't hurt and I can probably skip the seat for now?

What Bowl gasket do I need?

A couple years ago, I got a free mower with a blown engine. I bought a $150 used engine and I have been running it for the 3rd seasons now. It burns or leaks oil and if I don't use the fuel shout off when I put it away it leaks gas into the oil. I recently with your help figured out which engine I have (31C707-0154-E1).

I feel like I'm just not going to spend $135 on a carb from Briggs and Stratton on what's now an $80 engine.

someone on here said the engine was from 2004. That predates any vehicle engine that I own, it predates Facebook and Gmail.

I think I fixed the oil leak by tightening up the rocker cover, but we will see.

I hear the gas in the oil is a needle and seat issue.

I am feeling like a $20 Chinese carb is in my future.

Just put a fuel shut off valve in line and turn the gas off when not running
