I have had a couple 562's carbs stripped down, the first carb had a .021 low speed hole the later carbs have .022 ' hole , this is still to lean on idle so you either got to drill low hole bigger or make the notches in the butterfly smaller to let less air into motor on idle , I choose to drill the low hole bigger , I'm sure zama would of done this but to pass the EPA they had to make the saw idle very lean  , now when you hit the throttle on the 562's you get a bog then they come to life , mid range is to rich , they have 2 holes letting fuel in on mid range so you need to figure out how to resize these holes smaller , I blocked the next hole up from the idle circuit right off so only running 1 midrange hole now , that made a hell of alot better throttle response . Now playing with the stratos can make the mid clean up real nice , but you have to leave enough play for when you pull the choke on that only the butterfly moves in the main carb , if your moving the stratos butterfly when choking it makes cold starting abit harder cause your not getting full air pulling  threw main carb , now if you make your strato come on earlier your going to have to change the cam arm ratio cause you will end up with the stratos way over centre  so drilling a new hole in the strato butterfly arm is needed , Now this stuff is just me and what I do as like I said I hate running a saw that is not as close to perfect as I can get it
