I hate all the 'special' screw heads just to try and keep
people from turning them. I have several chain saws ,leaf
blowers, and other small engines that each one takes a
special tool just to adjust the carborator. Seems like
there are 5 or more special tools just to adjust the
carborators. One company does not offer their tool to
anyone but their service companies. I had to take my
Dremal tool and cut a slot in the head so a regular screw
driver would fit.

Those spcial tools only slow down people and do nt seem to
stop anyone.

Yep, that's pretty much the way things work. To protect the
environment from smog produced by chain saws, carburetors are to be
adjusted only by factory authorized experts, or by anyone with an eBay
account:

I find it hard that the accumulated smog output from small engines
would be significant, especially when compared to automobiles,
industrial output, and bovine flatulence, but so it is written into
the law.

Incidentally, I was just taking a break from chewing up some lumber
scrap with my nice new Stihl MS180 chain saw. The only user
accessible carburetor adjustment is the idle speed. No problem with a
new saw, but if I ever rebuild the carburetor, I'll surely need to
adjust the low and high speed screws.
