Starts and seems to run good and has real good compression (just from feel starting).

I made sure to fatten up everything with the missing muffler to fire off an see.  :o  Can you say she sounded like a racesaw  ;D.

Looks like I will needing a few parts but no biggie.

Do you still have a 372 to compare this saw too?

 These saws handle real nice with a 20" setup, as mentioned above if it didn't cut with a 18" setup some was wrong with the chain or bar, most likely the rakers too high.  These saws have the torque to handle a agressive chain.  Steve

Looking for max rpm specs on this saw. Right now I have it at 12K and just shy of 1 turn out on H with my 100% synthetic Klotz at 32:1.
Manual says L  1 1/2 to 2 5/8 out I settled on 1 1/8 -   H says 1 5/8 to 2 5/8 out and I went with just shy of 1 turn out to get  12k.  True the carb might need a kit and had sat for years before I got it.

Manual also says CAUTION always tune H side at least 1 5/8 out.  ???  It aint happening she would be so fat it would be a pig. Use commons sense on tuning IMHO.

Also never seen this in print before on sprocket rims wear.  When sprocket has worn out 0.5mm or .020 inch or more replace rim. Measured from top of rim to worn down area.

If you let them rim wear too much, the chain drive links will start stick through the rim and riding on the hub. The drive links will make cavities in the hub eventually.

Rain stopped so I got to do some test cuts.

Bucked some black walnut and ripped cut with 20" full comp in hard maple and soft spruce.  Reminds me of the husky 365 special cut wise.    Modified clutch cover was made for noodling  :D :D :D

I was impressed with this 67cc echo for sure  ;D. RPM WOT ended up 12.3k after the testing. Like it where she is at right now.
