Zenith Carb?

Postby John in Ct » Fri May 12, 2006 10:48 am

I was wondering :?: if anyone ever used a Zenith Carb on their Cub? How did the tractor run? Was there much linkage to change? Did you like it better than the IH 3 / 4 carb? Thanks.

John-

The late cubs all have Zeniths. There are several discussions about the ins and outs of the two kinds on here, and I'm sure someone will be along shortly to address the possibilities of changing between them. Good luck!

John, as Rusty pointed out, later model cubs have Zenith carbs. In addition, since the IH carb is no longe available, many cubs have been fitted with Zeniths. There is very little modification needed to accomplish the job. I believe most who have made the change are quite satisfied with the performance.

I have operated both. They both work well in my opinion.

John, both my cubs have been refitted with Zenith carbs, and I am very happy with the results. frequently it is necessary to bend the throttle to governor rod a little to clear the side of the block, and you will need a different coupling to hook your choke to it, and possibly double mounting gaskets to make throttle plate clear manifold throat.
If you are not part of the solution,
you are part of the problem!!!

Both carburetors perform equally well. Zenith gets an edge up because of it's overall robust design and complete parts availability, the IH has several design flaws that will gradually affect performance. The flaws are easily remedied. Most Cubs need minor modifications to use the Zenith. However, if the fuel entering the carburetor is contaminated with blobs of crud, both carburetors will perform equally lousy.

And don't forget that "PWL" sells the adapter sleeve to hook up the air cleaner tube to the Zenith :D

Brian - I believe it would have been 75.
