Whats up all!!
I've an NS12S3 with a bit of an idle issue and i think it's an air leak. I can get it needled in to idle nice and smooth but as soon as I kill it and re-start it she screams like you wouldn't believe. I needle her back down but now she will not hold an even idle she winds up real high them back down, she's all over the place. Any ideas???
Thanks,
Kevin
P.S. I have gone back to stock settings, same thing

lol

it sounds like an air leak, i would change the glow plug and check the head clearances to eliminate any factors.
