today i started my nrg and it was full reving its self, ive had a mess around with the tickover screw and it makes no differance, what could it be ?
sounds like youve got an air leek mate have a look at your manifold for any splits or tears also make sure everyting is tightened up properly round the carb area (manifold, jubilee clips, airbox etc)
just look for any rips or cracks and make sure all is tight mate but yes ive heard of peaple doing it this way
