engine troubles
 

hey all im new here
i hope this is the right place for my q's
i recently bought a HSP Tornado nitro buggy, with the Vertex .21 engine in it, i have had i for a week and i am already on my 3rd glo plug, also i have tried to tune it a number of times, it runs great somtimes then when i put a new tank of fuel in it, it runs fine down low but as soon as i open it up it runs for a couple of seconds then dies, i thought it might hav been a bit lean so i adjusted it with no sucess,
any idiea
thanks brent
