Zenith Carb on Non-Zenith Manifold

Postby Richard Sanders » Wed Apr 12, 2006 5:08 am

As a new owner of my first IH Cub, I'm learning something new everyday.

Seems that one of the previos owners of my '60 something standard Cub, bolted a Zenith carb to the non-Zenith manifold. I guess it ran OK (he's passed on, and I haven't started it since I bought it). Even though the bolt holes are in the right place, the flange area is much bigger on the carb than the manifold.

I'm going to make an adapter plate.

My question: What is the benefit of a Zenith Carb over the OEM IH carb?

Thanks,
Richard

Richard - no need for an adaptor plate. You might want to check the opening in the intake manifold, it should have a slight bevel which will allow room for the butterfly valve to move. The carb will work just fine on the standard manifold.
The Zenith carb is a replacement carb. It is slightly bigger but there is no significant difference in performance.

The main advantage to the Zenith is thye were and are still available, long after production of the IH carb ceased.
If you are not part of the solution,
you are part of the problem!!!

I have heard that some people had to use 2 gaskets so that the butterfly didn't hit the manifold but that is the only down side I know of.

Hey fellows, thanks for the quick replies and the warm welcome. Looks like I'm going to enjoy this site.

As far a pictures right now.....the old boy looks a little too rough for posing.

It was originally yellow, and someone painted it red, but now the red's chipping off and the yellow's showing thru everywhere.

Going to strip it down and go back with the yellow. When I gets him pretty, I'll send the pics.

Thanks again for the help and welcome wagon.

I had the same situation on my first Cub. I know its not an operational issue but I just didn't like the way the flange looked so I bought a manifold to match the Zenith. Only thing now is the new manifold requires a 1 1/4" npt - 1"npt reducer. I think all the manifolds designed for the Zenith have the large exit hole.

Richard:

First, Image to the greatest forum on the internet, and to the Cub Family. You will find that all the folks on this forum are kind, helpful and just full of Cub info and knowledge. They also happen to be the finest folks I have ever met :!: :D

As far a pictures right now.....the old boy looks a little too rough for posing.


I guess you haven't seen the Ugliest Cub Contest pics now have ya :!: :?: :idea: :shock: :? :?: 8) 8) :lol:

Ok, so here is the spiel Image:

I would suggest that you read this thread: New Members and Visitors, Please READ Prior to Posting. There are many great links to informative pages such as the ATIS FAQ's 1 and ATIS FAQ's 2, The Best of H.L. Chauvin who has written very interesting articles on troubleshooting common problems with your Cub.


Also, you might want to visit the Cub Manual Server as there is tons of info on servicing, maintaining and re-building your Cub. In addition to this basic information, there are also a number of other useful tools available on the server. There is the Specialty Services page which has contact info for neat stuff like getting your seats recovered, buying quality Decals, Serial Number tags and a host of other neat items. Also there are the Parts Pages - both Used Parts Suppliers and New Parts Suppliers pages with links to quality dealers. I am always looking for YOUR favourite dealers for New and Used Parts to include here. These are intended to complement the businesses who support FarmallCub.com Website.

I would also recommend that you visit Binder Books and purchase the three most important manuals you can own for Maintenance, Repair and Rebuilding your Cub. These are the Owner's Manual, the GSS-1411 Service Manual and the TC-37F Parts Manual. Although they are available on the Cub Manual Server, it is better is you also have your own paper copy. Binder Books is the only Authorized IH Publication Reprint House and they have the best quality manuals available. Most other's are not of the same quality. Just a personal thought here, the I&T Shop Manuals, although helpful in some areas, really are not sufficient for the job. If you wish though, they are good additional reference works.

IF you really want to get the skinny on all things Cub, might I suggest you get a copy of Ken Updike's Farmall Cub and Cub Cadet's :?: . Along with Guy Fay's Letter Series Originality Guide, these are two must have's in anyone's collection.

In addition to the above information, don't forget to check out the various articles that are available to help with your Repair, Restore, Rebuild or just your Maintenance Projects. There are a number of sub pages such as Electrolysis or Rust Zapper's, Maintenance Tips, Jigs and Techniques, Implement and Part Sketches and of course the Paint, Decals & Other Finish Questions which has the Paint Chart and the Paint Committee Decisions links.

I truly hope that you enjoy your Cub and that you will be a frequent contributor to the forum. Again, Image to the Cub FamilyImage :D

Boy Rudi,

When you post a reply....you really POST A REPLY!!!!!!!!

Thanks ever so much for ALL the info. I'd been surfing the net for this sort of info, and have a couple of the sites already bookmarked...but nowhere near the number you sent me.

This really is the nicest forum on the net. Cub guys are OK!!

Thanks again for taking all the time to help me,
Richard

I have the opposite situation, my manifold came off a numbered Lo Boy but has an IH carb. Never knew it was 'wrong' till someone told me on the board. It shouldn't matter at all, the hole into the manifold is the same size.

They must have changed the manifold on mine cause they needed an exhaust... but be warned the exhaust 'hole' is also larger and requires a bushing if you swap manifolds. My advise is don't give it another thought unless you have a problem.
