What's everybody's opinion on break in period on a new set of rings before I start milling? 32:1 ratio with the carb tuned a little rich for milling is what I've been reading, right or wrong? Any special oil/gas? Next is bar/chain size...I have the Granberg 36" mill already. I'll be milling smallish pistachio (18" diameter) and larger beetle Kill Pine (24"-30" diameter). Any experience with either of these types of wood? My thoughts are a 36" bar but I'm not sure what'll cut the best in the woods mentioned... (.375/.050), (.375/.063, or (.404/.063)? Also what's everyone using for a compression tester, would like to test my older chainsaws. I picked up a harbor freight one but with extension tube on I was getting false low readings (no Schrader valve at the end of the tube so I had to use those shorter ones with the rubber universal tip but that thing was a PITA! Thanks for all the input!
