Default problem with my os 46 ax

Hi guys, i wanted to go fly yesterday, it was a nice day here in quebec.... about 30 degrees. Got to the point of starting my engine....

filled the gas tank, closed up my needle valve totally and opened it like the os book says (1 1/2 to 2 turn countercolck wise). I did 2 turns. Hooked on my glow heater and started it...

At mid range of throttle i was disconnecting my glow driver, then full throttle for needle fine tuning adjustment. I had to close it up for uptimum engine setting... then i opend it up about 1/8 richer (i heard that it's good to do that, because the air in altitude is a bit more denser that at the ground level). Engine was reving fine .... from full throttle to idle ... with a good response..

At that point i was walking behind my plane while it was taxi-ing just before take of... well were is what happend... not even a minute after it was taxi-ing... at about 1/8 of throttle not even... has soon that i was applying just a bit of throttle for take off the engine died right away.

got the plane back to my stuf... retried... and same thing again...

I thought that i could have been of my glow plug, i had some spares... replaced it with a fresh one. But same thing occured...

Well, yesterday.... i spent about 2hours... just to try to get my plane to get to take off but without success!!![:@]


Now please.... please help me out....

I thought that it could maybe be my gas.... i am using the same gallon of gas that i used this summer... it's 15% nitro but there is really not much in there... could it be the gas that is not good anymore??

What else am i not understanding wight here??

have a nice one.
