Was the engine warm enough? Is the rotor phasing correct? Are both fuel and nitrous solenoids operating correctly? Just simple shit like this that often is ignored/overlooked, to start with.

thanks for the replys guys .... but yeah motor was warm , rotor phasing was good , had to swap out a progressive controller ....... mind you the car in question hasn't been touched in 5 years , owner swapped to a tighter converter last night we don't know if that is what cause the hiccup or not ..... I'm new to the top sportsman stuff sorry .... We got the car back up and running nothing was hurt we did melt a carb but other than that everything seems to be working now !!! ... I'll try to figure out how to post the video when I get back home .... thanks
