yea that sounds like wrongness. i have the CT5 with the new NX15 motor, and even without yanking the primer bulb yet and NOT USEING IT, i can prime it by pluggin the exhaust, give it 2 or3 prime pulls, add glow ignigter, let it set for about 15 seconds and its fired on pull 2 or is running by pull 4, this is a new only on tank 4 of break in still. runs great and yet to need a tune and only stalled 4 time since ititial startup and very first run on motor. and all 4 stall we re due to dry fueltank!!!! love it..
