Carb swap

Postby tbear » Fri Feb 03, 2017 3:49 pm

Hey, got a question about a 154 carb. that is total junk. They seem to get a small fortune for new ones. I inherited 2 brand new Briggs updraft carbs for a large hp cast iron engine. I'm thinking I could weld up a dual carb. adapter to bolt them up to the intake manifold on the 154, don't need the governor, just choke and throttle. Just wondered if anyone has done this before. All I use it for is to push snow, second gear at 1/2 throttle.

The Zenith carburetors for the numbered Cub low-boys are fairly easy to repair.

Suggest putting an ad in the "The Vine", want ad section of this site, for an individual to repair the carburetor. Several folks repair Cub carburetors.

Repairing the carburetor will be considerably less expensive than purchasing a new carburetor.

Not sure why you would go to the effort to mount two B&S carbs on a tractor. Second point, some of the B&S engines have more cubic inches than a standard Cub engine and the B&S carburetor would work if you could figure out the mounting and throttle and choke linkage.

We have tested a Briggs carb on my cub while we had it on the dyno and it worked well.Is was nice to be able to tune the main jet.the only issue that would have to be addressed is the throttle set up. Snap up some pix of your manifold when you build it there may be some members that might want to copy it.

What, exactly, is the problem with your carburetor?

There is no repair for the Lo Boy carb as it was vandalized with a rock or hammer before I bought it. I already own the Briggs carbs and by my calculations the 16hp Briggs was 533 CC or 32 CI and the Lo Boy is about 60 CI so dual carbs should give it plenty of fuel. Maybe I'll just try one first-might be enough. Know it would be simpler. I'll let you know how it works.

The Briggs carb you're considering is already larger than the Cub carb. One will be plenty. I've done that set-up, for dyno testing and it worked pretty well. I soldered an additional arm onto the throttle lever to connect it to the governor.

That would probably be a mistake.

Perhaps you would have less rigging to do by purchasing an IH carb off a cub. There are several people parting out tractors and IH carbs are well suited for the C-60 engine. Especially if you don't need the top end performance a zenith provides.

If you have a near by tractor salvage yard - measure up the bolt spacing where the carburetor matches the manifold. Search the salvage yard for a Zenith carburetor.

Zenith carburetors were mounted on quite a few different manufacturers machines, including Wisconsin engines. Some Zeniths have the adjustable main jet.
