Hello,
I have the Evolution 26GT - engine has about 2 gallons of fuel through it (40:1 mix), running APC 18x6W prop. Engine runs great, easy starts, good idle, transison, and it spins the APC prop at 8500..... but, - after every flight I have to wipe the bottom of the fuse - this thing is making just as big of a mess as the glow motors - am I still too rich? What am I doing wrong? I use the same fuel/oil mix in my DA-50 and it runs clean...... Any ideas?????????
