yeah, nt all the way...
usually the nt is easy start, prime if needed, whop, pop, its going instantly.
set toooo lean and they get hard to start. i was at the point of over 100 metres before firing. though boy did it go when running!
but a quick prime always made it start instantly
so. dismantle it, clean it. easy.
reassemble, check fuel level in bowl. adjust if needed.
try hitting the tickler and priming it. not usually needed. if it is, its lean. try raising the needle a notch. or two. failing that, rejet...
it can be hard to tune one to achieve easy starting AND decent mids and highs. theres things that affect it such as exhausts...
if priming doesnt get it to fire straight away, or it only really starts when spun fast...start sniffing around the ignition area instead..
and flooding will of course be easily seen by turning it over, and pulling the plug before its actually started. wet plug = flooded = fix carb
