Stihl 261. Starts when cold. Fails to restart when hot.

[TreePointer]

The two saws I own that had difficult restarts when hot were a Stihl 361 and a Dolmar 7900. The 361 issue was vapor lock, which was solved by cracking open the fuel cap immediately after turning off the saw. The 7900 had it's LOW carb jet tuned a little too lean. I turned the LOW screw out 1/8 turn to solve the problem.
