Here is a link to Stihl manuals, the HT 101 looks like it should help you out.....

The Stihl I rebuilt twice, same problem you have, then it fell out of a tree, cost to much to repair.
What I would recommend is some thing like this, either in a Tanaka or a Echo. It is much lighter and easier to handle.
