If it's not one thing, it's another, huh? OK...first, did you have the mower on it's side while you repaired the carburetor? That will soak the filter w/oil. Second, when the needle valve was leaking, it probably filled the crankcase with gas, making the oil very thin, and overfull. This is most likely the problem. Smell the oil, and check the level. If it appears very thin, and smells like gas, change it. Use 30wt oil.

Squeeze the oil out of the foam element and reinstall it. It should have a film of oil in it anyway...to keep the dust stuck to the filter instead of going into the engine.

Check these things out and let us know what you come up with.

Have you checked the oil level? is it too full? Worn rings and/or cylinder wall will cause blowby, filling the filter area w/oil. If the engine gets tilted far enough while running, it will also do this. Somehow too much oil is getting into the valve chamber, or the crankcase is filling with too much gas from the combustion chamber. How did the cylinder walls look when you had the head off?

You cleaned the cylinder walls with a wire wheel? That may be the cause. (or was it the valves you cleaned with a wire wheel?) These engines have aluminum cylinder walls, and won't take kindly to a wire wheel. If this is a cheap mower, I wouldn't put too much time and effort in it....I am not a Techumseh fan at all myself. I'm sure there are those who will disagree, but if all appears normal (oil level, no fuel in oil, etc...) I would say replace it, it's not worth your time. Buy a briggs or better yet, a honda.

If you would like to track down the cause of this problem and fix it, rather than pitch it, let us know. We'll be here to help.

Is the engine smoking when you have a clean air filter on??? Or try running it for a few minutes (clean environment) without the air filter. If it doesn't smoke, you probably didn't score your cylinder enough to matter. Cheese is right, don't ever put a wire brush on a cylinder surface.

If it is not smoking, check the following...
Over your valve springs you should have an "oil breather" sometimes this goes bad and lets oil to intake. Remove this breather and look on side which faces valve springs. The oil breather will have an internal disc which seals against the oil breather housing. If this disc isn't seated tightly against the housing it is most likely your problem.
Let us know what you find.
