You'd need something like this:
http://www.mfgsupply.com/m/c/32-9073.html
But since you probably don't have one of those or can justify the price, you
can probably do the following:
At WOT, keep turning the high speed jet richer until the saw "four-cycles".
This is a distinctive sound that a 2-cycle engine makes when it is running too
rich. You'll know it when you hear it.
Then, turn the high speed jet leaner until the "four-cycle" sound just goes
away.
Or just stop by a local small engine shop. They probably have a tach like
the one mentioned above and would probably be willing to adjust the carb for
you for nothing, or perhaps a beer...

Hi Mike
No the bbok says to adjust to the desired rpm only.
It doesn't say anything else about it.

Re: O.T. tach for chainsaw?
Hmmm a 4 stroke sound. Is that like when it's
sorta flooding out? Like putting the choke on
I plan on buying a new bar and chain for it
Maybe they'll put a tach on it for me if I do buy
the bar+chain. The local small engine shop I use
are pretty darn good. For parts anyway...
