Had an old chainsaw that I wanted to store with non ethanol fuel in it so I bought a can of Trufuel. The first thing that i noticed was that it was much harder to start and then when I got it started it idled rougher and at a lower RPM. When I adjusted the throttle screw it was not as sensitive as it was before. With the gas in it just a small turn of the screw made a big difference, I adjusted it to where the chain didn't move while idling. With the Trufuel in it the idle was too low and when I turned the screw not much changed, I turned it a full half turn and could barely get a rise in RPM at all. Does this stuff ignite/burn as easily as gasoline?
