Hi i brought a HPI Rush Evo for a mate with a basic pull start engine. But i am having trouble finding the right mixture for the car . It starts up but wont stay and cuts out as soon as i take out the glow starter. i know its not the glow plug because ive taken it out and tested it. If any one could help me out a bit it would be very helpfull as the kid is only 10 and it was an xmas prezzi. Thanks for taken the time to read this .

From Adam

P.S please right back a.s.a.p as i would like to know weather its somthing im doing wrong or weather i have broken it in any way.
