Mike Acres site says 16:1. I assume that was with old SAE 40 oil. Generally I get some 40:1 pre-mix I run in other saws and haven't had any issue. Do I need to mix some special thicker stuff for this one since its a bit older vintage? This one is one of the first ones off the line in I think 1966. Suggestions appreciated!
