One last thing. I trust very few peoples testimonials on oil quality. Most guys are so ignorant of what to look for, what they are actually seeing and what causes what they are seeing that their opinions are useless.Agreed, mostly. Your tune will NEED to go slightly richer for a 10:1 (ad absurdum example) because you’re introducing less burnable fuel into the engine per stroke.
Correct assuming good tuning and quality oil, and completely agreed. Until you hit the spark arrestor. Cooled, partially partially burned oil hitting a metal mesh surface creates predictable results. I know, just clean your #$%& spark arrestor once in awhile, no problem.
That slower burn of the oil should also have some effect on the timing itself. Faster burn…equals an advance? Having trouble visualizing the run right now, but I think that’s right. Probably a small change either way.
Also agreed on the terrible quality fuel as well. I’ve even seen problems from the canned premix stuff.
From the results people are having with the saber oil, it’s actually doing as good if not better job leaving a coating than the traditional mix oils. Another thing to monitor in actual use. I’ll be pulling muffler and checking the saw cold.
An example is the guys that uses Brand X super synthetic oil, pulls his motor apart after 5 hours of run time and the piston is bare metal. The guys then get on the internet and claim Brand X is the best and perfectly clean. The problem is a bare metal piston just proves they guy can't tune a carb to save his life and has nothing to do with oil.
