How can I adjust my Husky Chainsaw Carburetor?

I recently bought a Husky 266 SE chainsaw. The saw was in fairly good shape, but I decided to give it a nice cleanup and a new sparkplug, etc. After cleaning out the saw with an air hose, replacing the spark plug, I decided to pull the air filter. It's a K&N cone-shaped filter that mounts on the top of the saw. Finding it very dirty, I blew all the dirt out and proceeded to clean it and treat it with filter oil. The only problem is, the carb had been adjusted to match the negative air flow of the dirty air filter.

Now I have so much air getting in, that the saw will hardly idle and I have to constantly gun the throttle to keep it running. The high idle seems to be wrong also.

I'd like to adjust it and get ready for woodcutting season. Any advice on how to go about it? I have not been able to find a shop manual so far.
