John Deere 826 snowblower carburetor rebuild

It turns out the needle wasn't even connected to the float. Thats what the problem was all along. Oh well, now it has a nice clean carburetor.

where can i get a spark tester? and i always take the plug out and put it on a piece of metal and test it and im also wondering where i can get a carb rebuild kit for a briggs

You can get a spark tester at any auto parts store. I just usually pull the plug and set it on the head and pull it over. That works too.

As far as a carb rebuild kit, you can get them online or you can get them through a local tractor sales and service dealer. Thats what I usually do.

Hey Matt at 6:22 there is a round concaved plug on the left hand side of the inside of the carb. I bought a carb kit that included a replacement one of these. Do you know what it does or why I would want to replace it? Thanks for your expert advice.



PS: I think that John Deere might have been manufactured by Ariens but not sure. It sure looks like one and I know at one time they did make the JD snow blowers. Just a little food for thought.

That round concave thing at 6:22 is called a welch plug. There is usually two on a carburetor. Almost 99% of the time you don't have to replace them when doing a rebuild unless of course they are absolutely shot.

What do they do? How can you tell when they're "shot" ? Mine was covered in shit but I scraped it off. It surges at times but seems like it will do the job.  Did I just sell myself to the devil? AGAIN??

[mbyr31]

Well, the one you are refering to distributes air into the float bowl creating pressure to allow fuel to flow to the throat. The reason they do that is because of the manufacturing process of the carburetor.

As far as knowing when it's shot.... if it don't clean up, or has holes in it, it is shot. Then you need to replace them.

no help at all!

alright man thanks

yeah like to check the primer, dont even remove the shroud! just take the pipe off the carb and cover it with ur thumb and press the primer. if you hear air leaking out-theres your problem and then disassemble the shroud.

[jack9102]

thats an expansion plug they put in after machining/milling the entire thing. thats where a drill bit or something bored out the thing at several angles. its plugged so fuel or vaccum pressure doesn't go where it could affect the function of the carb.

well, i believe most tecumsehs suck but their snowblower motors werent that bad.. the lawn mower engines are pretty cheap to buy and fix too. but i agree on the fact that they're not as good as briggs and stratton...
