Carb choke lever

Postby john2189 » Sat Apr 02, 2022 2:04 pm

Do they make a small bushing to use the choke leaver from an ih carb to work on a zenith? The zenith shaft is way smaller and not even close to tightening. I have a makeshift cable on it not, but it doesn’t work that well

I have Zenith carbs on some of my tractors, and don't have a problem. Sometimes the lever hole (which originally had tiny splines) gets worn/enlarged over time. You might try removing the "pinch" screw and filing the slot that it pulls together with a nail file or similar, making the gap larger, which will allow the screw to pull the clamp tighter.

Hi,
Below is the listing at TM Tractor for a new choke arm, it says it fits both brands of carburetors.
You can look at the pics.

Below is a pic from TM Tractor of an original choke arm. :)

Cut a very small shim strip from a thin piece of stock ( usually a beer can for me but sometimes I have to find something thinner) and wrap around choke shaft and then install lever and tighten. Adjust coverage of shim as necessary for a tight fit

It would probably have to be at least a shim 1/16” thick. I have seen carb kits that have new choke shafts incuded. I will try to find one

Contact Morgan at McDonald Carb & Ignition. 706-367-4179. No sense buying a whole kit if you only need the shaft. Here’s what the shaft should look like.

I have the carb installed so you wouldn’t see much. I just wonder some how it distorted with pliers or something

I would cut a strip from an aluminum soda or beer can and wrap that around the shaft, as a shim. Costs nothing and if it doesn’t work, all you have lost is time.

Some Zenith parts are pretty pricey. I asked Morgan about a throttle shaft for another model Zenith, he told me it would be over $100 if he could even get it. I settled for just rebushing it and accepted a little slop. For this one, I would just make a new lever to fit your shaft.

Wow! I guess for that much, I can put up with my makeshift choke cable. It works, just doesn’t look pretty.

As they said, you can make one yourself out of small rod stock. I just had to do that for my JD B and it was easy.
