I have a Stihl FS81 that has been an excellent machine, easy to use. But after setting up all winter and half the summer, the pull rope won't turn the engine over. I shot some WD-40 into the spark plug hole and let it set. No luck. So I took off the breather and squirted Kroil into the intake valve. So far nothing. I wonder if the last batch of fuel mix might have been short on oil. Every screw on this machine has a torx head, but none in my assortment fits exactly. Where can I buy the proper size?

not sure what to tell you on the problem.but lowes or any autoparts would have the bits you are looking for.

to me, it seems like almost all small engines that have torx bits, use a T-25 in case you don't have one

Wal-Mart may even have Torx sets, these engines will use Torx in the T-25 to T-30 range. I use mostly 1/4 inch drive ratchet.
