Cat 22 carb tricks???

My very early 22 has a Zenith K5A that is leaking from sitting too long. I am going to get a kit and rebuild it. Are there any tricks to a K5A that are like the D2 pony lead seal or any other things unusual to look for? Any recommendation on a supplier? Thanks, Grant.

I would look at what part of the carb is leaking and focus on that. I have decided that perfection is temporary on something that isn’t operated often.

When I did ours, I didn't do anything special other than clean it and blow out the open passages and jets. Put a kit in it and it's work flawlessly since - 20 years or more and it only runs once per year. Starts on the first or second crank over every time.

If you take it apart, be careful not to break the venturi tube.

Yes, I have been warned about the venturi tube. I will be careful. I will take it off of the machine today and start removing what looks like 10 coats of paint. I think that I will take it apart before I start soaking in Carb cleaner. I dont know what the float material is, and dont want to damage it.

I am sure I will have more questions once I am into it. Thanks.

Morning GrantJ, greetings from South Africa. We are Third World here, so my question is , where do i get a carb kit for my 22 1j5125sp. Our Caterpillar dealer , Barlows are expensive and not help full with vintage stuff.

Thanks Wayne
