I have a prob startin my engine. Its an Evolution .46NT (2-stroke, bearing engine) Last night I started it for the first time. I primed it, put the glow driver on, and turned it over with a chicken stick...all as per the instructions. after about 2 minutes, it was firing, but just sputtering and not steadily firing. another minute, and I had it going. let it idle for 1/2 a minute, then slowly revved it up then back down and took the glow driver off, as per the instructions. Then I tuned it like the instructions told me to do... with the hispeed needle valve, you have to pinch the fuel line and listen to see how much it rev's up before it dies, then adjust it accordingly. (i put that in because I dont know if that is how you tune all motors) After It was warmed up, it would start on the 1st or 2nd flick easily, and when it was running, it didnt backfire or miss or anything, even with the glowdriver off. just after I figured I had it all goin good and tuned, (I was going to run a tank through it to break it in) I tried to start it... and it wouldn't go!! it wasn't even firing at all, no sputtering, nothing!! I changed the glowplug. nothing. changed the battery in the glow driver. nothing. didnt get anything out of it. So i drained the tank, put some after-run in the motor, and left it overnight. Tried again this afternoon, but same deal. it doesnt even fire for a second. help, please?

I noticed something, i dont know what it is. After I packed away the plane and stuff, I noticed that on the cement pad I ran the plane on, there was this brownish-clear thick gunk where the exhaust would've been pointing, and there's also a thin film of that on the plane. I'll give you some #'s on the fuel... it says 5% SPORT FUEL SYN: 75%, CAS: 25%, the brand is Xtra Performance. This is what was recommended to me at the LHS. The manual for the motor recommended atleast 10%, and i told the guy, but he said 5% is good enough.
