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)....

No problem.  I'm glad you learned that one without getting hurt.   I was lucky too.  Had a clutch unwind to within 1/2 turn of coming off.  Watched it spinning off after I'd killed the engine. That was before I worked in that shop (and heard the story about the holes in the roof from the old timers)...

LOL.  My posts on this site are the closest I'd likely come to putting something together like that.  I'll be rebuilding a 25DA and a Micro or two sometime later on.

Cur4Fun has really put something special together here.  There's an amazing amount of knowledge in this site.......both in the membership and in what they post.  Many different areas of expertise/knowledge represented here.  Many different interests within the chainsaw hobby/industry here.  Modern saws, race saws/chains, 'antiques', etc.   Several folks here have a breathtaking amount of knowledge about subjects that I know little if anything about.

I've contributed some stuff (hopefully useful to folks), and many others have too.  I still owe the site several write-ups that Cut4fun has asked me to put together.  As I get caught up on projects I'll post more stuff up...

There were a few Micro variations with differing forms/levels of AV.  130 psi is good for a Micro, even a new one.  May be one of the variants with a chromed cylinder and bare piston.  Most Micro series saws have a chromed piston and bare bore.  Still good engines, but the chromed cylinder variants usually have a bit more compression and power.  Take any pics?
