1941 John Deere B

Til Valhalla · Jan 22, 2021

I have recently bought a 1941 John Deere B and was wanting to convert it to a pulling tractor but wanted to maintain the initial integrity of the machine.

The thing floods constantly and won't start.

I think that I need to clean the carb and maybe replace it.
There are other things that need to happen to it but I have either done it already or need to do it.

Looking for any potential advice.

Thanks

Start with KISS keep it simple stupid.

Take the carb off and check it out. Could have a bad float or rust/dirt in the needle seat or other such things. Clean it up good and put a kit in it and maybe a new float and then go from there. Trouble shoot never throw parts at things till you know what the problem REALLY is

Most flooding is caused from a contaminated tank.

If the fuel supply is not clean it WILL flood.

If the tank is original, real good chance it is flaking rust and will be an ongoing problem until it is corrected. Inline filters are not a good choice, too restrictive.

When you say it floods, you mean after letting the tractor sit for hours it floods? Most old tractors use gravity for a fuel pump and needs a cut off valve on the tank so you can shut the gas off when you are done with it.

It does have a gravity fed fuel system in it and I double checked everytime that we tried to turn it on that it was off when we were done. Now that I have gotten some replies I am pretty sure that there may be some rust flakes in the fuel lines and the carb cus the tank is original and is in bad shape.
Thanks for the advice everyone.

Depending on what type of carb drain it has open or remove the carb drain plug then set a pan to catch the gas under the carb and turn on the gas. Let the gas flow for say 3-5 minutes then look the gas over real well for dirt/rust etc. Rust/dirt will keep a float needle from seating

You might drain the tank and see what it looks like inside. If the inside is rusting you might clean it up and put a fuel tank liner in it before it develops big holes. The liner would certainly stop any flow of debris. You may also have a problem with debris in the
carburetor keeping the seat valve from closing. Then if it has a hollow float in it, it's possible it may have filled up with fuel and not working.

The tank is dryer than bones right now because last time we ran it we ran it dry so we could work on it in the winter. But when I shine a light in both tanks I can obviously see rust flakes.

I have 2 gal aluminium fuel tanks on both
my pulling tractors. Have the little tank
under the hood of my 435 JD. So you fill
it in original place. Don't want to put
any more than that much fuel in them
anyways. Does it have a little gas tank?
Just clean it. No need to have 50-60
pounds of extra expensive fuel.
