Cub 100 carb question

[mfrade]

it's only got 3 moving parts.. most easily fixed.. what makes you think it's "shot"? It's your money - spend it as you see fit. But don't toss out that old carb. it's pretty easy to restore and it seems like someone on here is always searching for it.

If the "shot-ness" about the carb is a bunch of play in the throttle shaft, CC Specialties has the copper bushing you need to fix that. My 106 is gonna be getting one this spring. Not too hard to do, just gotta drill out the aluminum and press in the bushing with a bit of loctite on the outside of it and you're good to go.

I took the bowl off and the body is deteriorated to the point of pieces flaking off.

It could just be some aluminum corrosion or some gunk from gas residue. Post a pic of this area, you might be able to clean it all off with a wire brush and still use the carb.

It was just corroded badly. I’ve never seen a carb this bad. I’ve spent several hours cleaning on it. A local dealer had a rebuild kit for it. I’m surprised the thing ran at all.

That looks just like the one I bought for my 107. The choke is correct, but in order to get the throttle to work you'll have to steal the ball joint off the old carb and attach it to the new one.

Just use a heim joint.

Try your part # on EBay. I scored a NOS carb six months ago. Of course, NOS ain’t gonna be cheap.

I got the carb cleaned. I’m going to install it after while, hopefully it will run.
