I did that one time and I thought I had it tight.   It was in the garage and pieces were every where.

When at work I check saws all the time with the clutch cover off so I can look for oil coming from the oiler.    I do not rev them to high though, I don't want to loose a clutch there.

The trick is not to repeatedly blip the throttle. ;D

The 'trick' is to NEVER start the saw without a bar/chain on it right after installing the clutch.  Put a bar and chain on it and run it for a minute or so (with several 'revs') first.  That'll tighten the clutch tighter than you can with a wrench (without breaking anything).  Then you can safely run it with the bar/chain off if you really feel the need to do so....

That clutch can do serious damage to people and property when it comes off/apart.  I worked at an old shop with a high tin roof and tin walls.  There were several shrapnel holes in the roof and one wall over/next to one of the benches.   Years before I got there, some guy did the no-chain rev up thing after reinstalling a clutch.  He was seriously injured (along with the damage to the roof and wall)....

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.
