I am working on a Stihl 028av and am having a problem getting the choke to close fully. It seems that the air filter/choke should have some sort of gasket between it and the carburetor. The Start/choke switch doesn't lock completely in place. I can get it to choke if I push and hold the thing, but the choke runs out of travel before I can get the lever fully locked. Any help would be appreciated as I don't have a manual or parts diagram.

There isn't any gaskets between the air filter and the carburetor. I would look closely at the switch shaft and the contact spring , make sure there is nothing broken or missing on the shaft, also make sure the spring is not bent or out of place. I have also worked on saws where the user has over tightened the air filter and deformed it so the choke would not work correctly.

Just wanted to say thanks! It turned out to be that the air cleaner was deformed, as you thought. Got a new one and it works fine
