My brother-in-law has sugested that i could use his plumbing gas analyser to adjust the fueling on my NC23.

Has anyone tried this and what sort of reading should i be looking for to show a correct fuel/air ratio.

Thanks

Just take it to a dyno matey. no point messing about with it with the wrong kit and no skills to adjust it correctly.

Best money you'll spend and its not that expensive anyway.
