Hi
5-15% nitro is all you need.
are you sure you spin the prop counter clockwise!? And that you have opened the highspeed needle enough?? (2-3 turns ).

When you turn the prop by hand, holding a finger over the carb intake, you should see fuel comming in the fuel line too the carb. Can you see this?
How does your glow starter work?
You should have a 12V, 10A Motorcycle battery and an automatic glowdriver!
Holding the glowplug in your hand it should lit with a bright yellow/white/orange glow...not dull red!
Those small 1,2V Nicad one-cell devises are not that good!
