Hi me again. Pls help! My NC30 starts, sounds power, acceleration is sweet but then from 7k rpm it starts spluttering,wont rev cleanly and pops. These symptoms are constant but every now and then its pulls right thru very powerfully. I did the fuel tap mod and also put in an inline tap to prevent flooding but it seems to be leakin as the diaphram is buckled. What can i do? thanks
