Choke lever question

Postby bullmack » Sat Aug 14, 2021 10:42 am

My '49 cub has an IH carb. The choke lever that is on it is pictured and it's cracked. (left side, at the bottom of the slot) I bought a replacement lever from TM and the hole for the choke shaft is too large. I would also note that the choke shaft on my carb is splined on the lever end. Any help to procure a correct fitting choke lever would be appreciated. I plan to try some JB weld to repair the crack on my lever, however, crack is through and through.

The slot at the top of your lever in the picture should be the same width as the short, narrow slot at the bottom. I really doubt that JB will be strong enough to hold that together when you tighten the bolt on the shaft. The choke shaft should have splines. You might be able to shim the TM lever with some narrow strips of pop can.

Hi,
Below is the listing at TM Tractor for a new choke lever, it should fit like they show in the pics.

http://www.tmtractor.com/new/fl/522fp.htm

Below is a pic from TM Tractor of an original style choke lever on the choke shaft.
The lever usually has to be in about this position when the choke valve is fully open, if the choke rod is the original length.

The 2nd pic below shows how the choke rod fits, it should be slightly above the Touch Control tubes.
If the rod rubs on the tubes, the engine vibration can wear it into the tubes over time.
If the rod is too low at the tubes, increasing the bend in the pic will probably raise it up.
You probably need to remove the rod to bend it. :)

I have the TM choke lever. The metal closes together at the screw before it closes tight on the choke shaft. The only way I can make it work will be to open up the gap at the screw or possibly wrap the shaft with something to make it's diameter larger.

One side of my choke lever broke off. Drilled a small diameter hole through both sides below the break. Inserted a small bolt, lock washer, and nut.
I have an excuse. CRS.
