Minimal Compression

[Shaunzo]

Lifetime weekend warrior wrestling with a CS-4600 to determine who’s gonna be boss.
What’s minimum compression this saw should still start and run ?
This thing is flooding like crazy and I can’t figure out why. Ty

Diaphragm? I like to see 90 to 100 on a whipped saw.

Yup.... 100 or less is the standard for a more detailed look into the internals or gasket/seal leaks.

I have worked on an old grey body Echo SRM-210 string trimmer that had 81 and it still started and ran decent... power was a bit low of course.

The guy is still running it as far as I know!

Not sure how they do it but those 21. 2 cc beasts will run almost perfect even with a roasted cylinder
