That's surprising considering how many threads there are here about this. This is a very comprehensive article and if it doesn't explain it well enough for you I don't know what will. So I hope it helps. http://madsens1.com/saw%20carb%20tune.htm
There is a ton of info using the search function.
I put some of it together as part of an FAQ thread here.
has anyone got a simple but effective way of tuning a carb, i have had a look on here but havent had much luck, does any one know of a good link or site thanks.
Just run both screws in until they just touch the seat, don't go to far. Now Back them both out 1 1/4 rounds and it'll be so close it ain't funny then fine tune it by ear. Good smooth idle and four stroking at WOT.
If the saw has a muffler mod. be sure to richen up the high speed to allow for it. Saw Safe.

so from what i have read L for the right mix and H for rpm, so if i turn up H clockwise to get more rpm for my saw will i have to adjust the L? and if i get my saw to idle smoothly with the L needle then just adjust the h needle for the rpms? is this right?
can you tuna piano with the same screwdriver?

Not exactly. Lo and Hi typically operate independently. Once saw is warm turn Lo screw counterclockwise until saw starts to stumble. Then turn clockwise until same thing happens. Midway between both were you set Lo screw. Now you set idle screw. Test settiings by seeing whether saw revs smoothly w/o stumbling. Next you set Hi speed as discussed in earlier posts. However don't lean out too far(turn clockwise) or you'll burn up saw. I listen for fourstroking sond and then rev saw up and shut it off under WOT. This way I can check color of plug. You're looking for a light brown color. If its more white in color your Hi speed needle is set too lean. Turn it counterclockwise and retest.
