ethanol

[RM]

I'd be worried that E20 would run excessively lean with stock jetting. See: http://www.ethanolproducer.com/article.jsp?article_id=5273&q=&page=2 "Unlike some on-road vehicles with sophisticated closed-loop operation capability, small engines generally aren t equipped to adjust fuel/air ratio and apply long-term fuel trim. Thus, when small engines like those found on chain saws or weed eaters are run on intermediate ethanol blends, they tend to run leaner and therefore hotter. These open-loop engines are commonly air-cooled, and they customarily operate fuel-rich to achieve cooler combustion temperatures for longevity purposes, the report states. With a fixed fueling calibration, as ethanol content in the fuel increases, combustion becomes leaner, leading to higher combustion temperatures and higher component temperatures, as well as changes in emissions and sometimes idle speed."
