Problem rebuilding Cat 10 Ensign Carbs

Well, here is is my experience. The ensign carb on my PV-15 does the same thing. I'm told the float is sticking. I get gas running out the bottm of the carb and it makes a mess.. I tap the side of the carb and is usually frees it up and it starts.

The carb has been completley rebuilt and it still does it. I'm on my second flloat which has helped the situation.

I have another tractor with the same type carb and I never have any trouble with it.

Dunefanatic,

Your float can be just fine...but if the needle and seat are bad, it will always leak fuel out the bottom of the carburetor. Mine does, but not real bad. I could not find a needle and seat to match mine (non standard) so I had to try and hone the surfaces to true them up. I was close but not exact. I have just gotten use to cutting off the fuel and letting the engine burn off what is in the carburetor to shut down.

If those gaskets are not EXACT (top and bottom of venturi tube) fuel will leak by the bottom one too. But usually if fuel leaks by...the tractor will not start either. It needs to make a good seal for any air or fuel to atomize in that chamber. You know you have it right when you assemble the top and bottom halves of the carburetor, the top cover should have a tiny gap between it and the bowl gasket. When you put the screws in and tighten them up, it will pull everything tight! Over time those gaskets can dry out and shrink.

Greg,
If you figure it out, let me know as I have a High Ten doing the exact same thing.

I am watching this thread closley for future referance, I have found a product called seal all that comes in a yellow tube with red trim, its cheap and will stand up to gas, I think better than rtv in a gas application, usually available in autoparts and hardwares. Looks and acts like clear contact cement.

Is this the stuff that claims to work on leaky fuel tanks? I haven't used it in a long time but I remember it being impervious to gasoline.

My Ten has the opposite problem. It runs fine under load and at higher rpms, but I have to leave the choke on 3/4 or so to keep it from surging at an idle. Any suggestions before I take it apart. The idle mixture screw doesn't seem to have much of an effect.
Thanks, Jim

Jim,
These carbs were not exactly top notch for their day. The screws on my carbs do not do a whole lot either. I sure have seen a lot of 10's and PV 15's with some other make of carb modified to work on them.
