Best tool for dissassembling a 2 stroke mill or any mechanical part on your sled or atv etc. is a
parts "explosion" drawing. These will show you exactly how all the parts relate to one another

A good explosion drawing will even give enough detail that you would have to be a dope smokin neanderthal to screw things up. Great for reassembly too ofcourse.
You can get these drawings from part fisches online. I use them all the time.
As mentioned many times above... a proper manual and a good set of tools blended with a touch of mechanical know how and you're good to go
Oh yah... BEER
