Deere B Carb

[garjess]

I'm working on a Deere B with a DLTX ?2 carb. I can't find a breakdown of a carb that matches mine.

The bowl is held on by the large nut on the far left of the pic. That is, I think, 5/8 coarse thread (definitely coarse). The hex head on the right of the pic is between the nut and the bowl. The three washers or spacers were between the two.
So from the bottom: Large nut,spacer, spacer, washer, Hex head fitting, gasket, bowl.
I need to ID this so I can order parts.
Sorry for the lack of pics, I didn't think it would be a problem to ID so I only took the one pic and its storming outside now.
Hopefully someone will know by reading my terrible description.

I think your carb has been -how should I say it- slightly modified. Check out the parts diagram to see how it is supposed to be put together. All the parts are readily available..

This one is from an unstyled B

After looking online for a while I was suspecting it had been slightly modified. I'll post pics of the actual carb tomorrow, nothing inside the bowl looks like the drawings I've seen.

Look on Roberts Carburetor site or get their catalog.

Here's what I'm dealing with. I see where the fine threads should be but they are stripped nearly smooth.
The problem I have is getting it to seal around the gigantic threads. Maybe some form-a-gasket will work.
Anyone have suggestions on a better sealant for coarse threads and gasoline?

I don't know what your plans are for the tractor, or what your financial thoughts are, but those carbs are pretty common. I would replace the carb with one that
hasn't been modified. The load nozzle is inside the stem that the threaded rod (or bolt) is coming out of. That nozzle needs to be pulled and cleaned to truly
clean the carb. There are also drilled passages at the base of that stem that determine fuel flow for idling.

Now for the amazing part. I cleaned the bowl. That was the dirtiest carb I've ever seen! Piles of varnish and rust.
Put the bowl back on with some makeshift o-ring.
Cranked it up, first time its ran in 11 years. The thing runs like a top, idles, revs, pulls, everything I ask of it it did.
It leaked some out the bottom of the bowl but I'm sure I can stop that.
I love old stuff! That thing will be running when my Kubota is in the scrap yard.
