New Member, Old Cub

Saw this Cub and had to buy it, I think it is a 1959 model, serial no. 213710. Runs great and looks good but when you shut it off it floods and will not start until the bowl is drained and left to dry a bit. The previous owner put on a $30 dollar Amazon carb. What carb would be the best to replace it with that is a decent price? I grew up with Farmalls in the 50s M,MTA, A so it is great to have another.

[Jim Becker]

The previous owner didn't happen to save the original carb and pass it along to you did he? If so, fix it. If not, first thing I would try is to open up the one you have and adjust the float level and float drop.

Take the carb off and set the float. Those carbs usually work well but they all need to have the float set correctly as they are not set correctly from the factory. That's the first thing I did with mine.

[Jose Wales]

The former owner adjusted the carb several times and then took it to a repair shop and had it rebuilt and it still floods so I thought I would replace it. What carb would you recommend for a replacement?

[Don McCombs]

I would recommend you adjust the float, as advised, before you spend the money to replace it.

[Jose Wales]

Thanks Don, I will take your advice, I had it running this morning and it just runs great, did have trouble starting it at first. I think alot of it is you just need to take time to understand the tractor and what it wants ????

Everyone mentions the float which is good as l've suffered that problem as well. If you're taking it apart check the needle valve. After all that's what the float operates. Maybe think about changing it out before scrapping the whole carb.

By the way, welcome to the forum. As you can see, lot's of advice here for your problems.

If you're dead set on a new or rebuilt carb, put a WTB in the vine. There are members that rebuild and sell carbs.

Welcome to the Forum! Congrats on the new-to-you Cub.

Take some time and read through a few threads to acquaint yourself with the Forum:

• Using the Forum

Don't know if you have any of the manuals to your Cub, but now that you’ve logged your 2nd post, you'll have access to the all the PDF Manuals on this site. There’s a few ways to do that:

• From a desktop or laptop, go to "Quick Links" in the upper left corner of your screen. Hit that and a pull-down appears where you'll find "PDF Manuals".
• You can also go to “Cub Info” in the upper toolbar, then hit “Rudi’s Manuals”. From there, you can access a variety of information.
• If you're using a phone, go to the "Links Directory" (second category down the main page). Once in "Links Directory" , scroll down to the second section "Tractor Parts & Manuals" and you'll find them there.

You'll be able to download an Owner's Manual (very strongly recommended) and any service manuals that interest you. Implement Manuals are also available.

We’d encourage you to take the Safety Test located in the Safety Forum: http://farmallcub.com/phpBB2/viewtopic.php?f=33&t=68084

There are a lot of good threads dealing with Cub repair (especially fuel-related) and maintenance in the How To Forum. Located here: http://farmallcub.com/phpBB2/viewforum.php?f=11

Take some pictures of your tractors and post them, we’d like to see them.

You say when you turn it off it floods. The above advise is good but in the meantime shut off the gas valve at the sediment bowl when you turn it off until you get it adjusted properly.

Hi,
People have said on here that their carburetor didn't work right until they set the float level exactly.

Here is info for setting the float level and float drop for the IH carb.
Below is a page from the Cub service manual showing setting the float height.
The IH carburetor is in the upper pics on the page, the Zenith carb in the lower pics.
You have to take the carb apart to set the float height, and float drop.
When taking it apart, pull the 2 halves of the carb straight apart several inches, there is a small idle tube that screws into the top half of the carb, it can break if you twist it, or don't pull the 2 halves straight apart.
I guess your carb is nearly new, but all the passages need to be open and clean.
Blow them out with compressed air, and be sure they are open. Use your safety goggles when using the air.
The needle and seat could have dirt in it, making it not seal. Remove the float and the needle and check for dirt, clean the needle and seat.
Assemble the needle and float again.
To set the float level, turn the top half of the carb upside down, like the pic of the Zenith carb, in the lower right of the page.
The gasket between the halves has to be off, when measuring the float level of the IH carb.

http://www.farmallcub.info/manuals/gss- ... 002-09.jpg

Bob McCarty converted the measurements to use a dial caliper, it is easier.
The float level is 1.4"
The float drop is 1.6"

The stop on the float arm has to face up.
Sometimes the float is upside down.
Put it in the right way, if it is upside down.
Bend the float arm between the float and where the needle touches it, to change the float height.

Turn the top half right side up to set the float drop.
Bend the stop in or out to change the float drop.

The needle and seat could be defective, and don't seal, then the carb can drip on the ground when the Cub is sitting.
If it doesn't work right after setting the float height and drop, the needle and seat might need replacing, if it floods, or drips.
The IH carb has a small screen where the gas line attaches to the carb, be sure it is clean.
Tighten everything on the carb gently, the IH carb is soft metal, and threads can strip.
The carb top can warp if the screws are tightened too much.
TM Tractor, at the bottom of the page, has new carb parts.

Cubs have a manual choke, you have to use the right amount of choke when the engine is cold, until it warms up, so it runs good.

Below is a pic of an IH carb float from TM Tractor.

Thanks for all the help, you are a great bunch of guys. I will do my homework on your suggestions and post the results. It started a while ago after draining the bowl and letting it set for a while. I do shut off the fuel line when not running but it sure runs great when running. Can a short video be posted of it running? If so I made one to post.

[Bob McCarty]

Go ahead and post the video. Perfectly acceptable.

Hi,
The Cub operator's manual can help you learn about maintenance that the Cub needs.

Below is the 1959 Cub and LoBoy operator's manual. The experts on here recommend people read it. It has lots of info about operation, maintenance, and lubrication. There is a table of contents on page 2.
The index begins on page 46.
It shows how Cubs originally looked in it. The lube section begins on page 36.

http://farmallcub.com/rudi_cub/www.clea ... index.html

It shows the electrical system that a 1959 Cub originally had.
Cubs made before mid 1964 originally had 6 volt, positive ground electrical systems.

The Hy-Tran fluid mentioned in the manual is Case IH Hy-Tran fluid nowadays. It is sold at Case IH dealers.

I would check or change all the oils before using the Cub. Using it with low oil in a gear housing can damage the parts in the housing.
There are 3 separate gear housings, with 3 separate oil levels to check, in the rear area of a Cub, the transmission, and 2 final drives.

The transmissions in Cubs commonly get water in them, from rain, or condensation inside the housing over time.

The 1955 Cub operator's manual below has more info in it than the 1959 manual above.
You can read it if you don't find what you need in the 1959 manual.

In addition to the help already offered, if you’re a visual learner (like me) and need to see pictures, then go back up to my post and click on the link to the How To Forum. Go to the Fuel section and start going through Luke’s Carl’s posts at the top of the page.

[Jose Wales]

Thanks for the help. I checked the gas tank and it is really rusted. I think the first thing I will do is clean and coat the tank,clean the bowl and new inline filter before trying to adjust the carb. Then follow the What to do when bringing a new cub home, that is a great thread.
