Air Intake Tube

[Urbish]

If you have an early cub may be considering getting an IH carb and using the standard tube. I think the early cubs do not run as well on the zeniths but I am not as familiar with the zeniths do I do not know if they are in as good a shape as my IH carbs.

My '48 runs like a champ on a Zenith carb. That said, I have no idea if the previous owner messed with the jets or anything. I'm leaving good-enough alone.

if you have the metal tube with the stock IH carb slip another piece of a lower radiator hose over the original hose, it makes a perfect adapter from that hose to the zenith carb

My 1953 CJ3B has the wrong engine in it (out of a CJ2A). So the stock formed sheetmetal/tube air cleaner pipe setup for either engine will not correctly bridge the gap between the carburetor and the oil bath air cleaner. I made my own air intake hose out of a radiator hose with the correct bends. However, it is too small diameter to fit neatly onto the carburetor. So I did as others suggested here, putting a short stub of smaller diameter hose inside the larger one with a hose clamp on the outside. However, there would be nothing but the rigidity of the doubled up hose for the clamp to tighten against, so I cut a short stub of thin wall PVC pipe to put inside the smaller hose. So there's three layers: PVC pipe, smaller hose, then larger hose, with a clamp binding down on all three. This has worked great for about 12 years now and the hose quit falling off every time I hit a bump.

I appreciate all of the helpful suggestions. I called Hamilton Bob's and talked to them to see what they had to offer. In the end, I decided to buy the rubber hose from TM that way I only had to buy 1 item and I thought it would look cleaner.

That's a sweet looking Cub!! Mine won't look like that, it's just getting a mechanical rebuild and I'll be sending it down the road.

I had one that I set up with a larger tube over the Zenith, and a smaller one inside it for the air pipe that I used for several years that way. It was very difficult to tell it was not a single hose. Be sure to use air hose rather than radiator hose though. The air hose with stands the deterioration caused by the gas fumes that drift back into it after engine shut down better than radiator hose does.
