SRT..................up here north of the border, we don't have stations that carry E-85, so the only option is to use the regular gasoline. I have NIB a SAITO FG20CC engine and I intend to test bench this engine in the spring or summer. I have no big rush, I've heard quite a bit of negative comments about this engine, one being that it runs good on ground but fails in flight. I would like some one on this thread who has this engine to explain the best way to successfully have this engine tuned in properly. When you hear about these negative comments one is fairly disappointed and discouraged to the point where it becomes doubtful that this engine is anything but a show engine. I purchased this engine at the TOLEDO show 2011. Has there been any changes in the carb prior 2011 ? Those who were successful and happy with this engine, did they follow the instructions in the manual diligently ? I would like to get some feed back from the experienced guys. Thanks.
I would say that the problem would most likely be in the carburater as there is no other difference between your FG20 & the FA 125 aside from the ignition system.
I looked in the Saito manuals & there is no mention on setting up the spark timing. This is ludicrous IMO. However, spark timing should not make for differing performance in the air when the engine runs fine on the ground.
For some reason Saito seems to think that gasoline needs a pump for delivery when there is no such requirement for most glow engines aside from the 300TTDP. even glow engines tend to lean out when "in the air" so perhaps that is the problem W/the gas engines. Setting it up a bit "rich' might be all that is needed.
BTW: there is E-85 available a lot closer to you than me.
Check here.

There appears to be an E-85 station in Guelph.
You will should get between 15% to 20% more HP from alchohol fuel.

Here are some FG 20s running on E-85
