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)...

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.

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?
