I can't remember off the top of my head but what's the standard cab settings for a husqvarna 2100?
There are no 'standard' settings for a saw carburetor. Each saw will need to be tuned to the conditions (temperature, humidity, elevation, fuel quality, etc). Mike gave you the initial settings. Seat the saw at those and tune from there.
I'm thinking that the slight miss you're hearing is 4-stroking. I hope you aren't trying to tune the saw so that it runs clean at WOT out of the cut. That'll make it lean out under load. Tune that saw per my sig line.
Also, that saw has a high speed governor valve in the carburetor. It's supposed to open up and richen the mixture when the engine hits a certain RPM. That can cause a fellow to think the saw is 4-stroking (and therefore properly tuned) at WOT unloaded when it is in fact still too lean. For governed saws, you really have to tune it in the wood. Get it warmed up and then get into a cut. When you lift the cutting load, it should 4-stroke right away.
