help needed - the two screws on the card

[Blunet600]

help please. I checked out my spark plug and it was a quite black, so i cleaned it, and thought i shoudl adjust the mix, now i chaged the idle screw - the big one, my questions for that is - does the big screw only adjust the idel speed?
second queston is i ajust the smaller screw and ended up turning it alot (why? coz im an idiot) to the left, didnt count how many clciks or anything, the biek was comepltley different, my mate had a go and said it i running lean, now what the fuck have i odne, have i done any long term damage? ho wwill i know that it is back to how it was b4 i fucked around with it? help please.....

use the search function and look for the manufacturers manual links thingy bob, it will tell you the factory settings on your cab

The big screw on the side of the carb is purely for adjusting the idle speed, the smaller screw usually slightly reset is the idle mixture, this shouldn't need touched but i guess you did.
Screw it clockwise very gently until you feel it stop, don't force it, then turn it anti-clockwise 1 and a half to 2 turns, this is a basic setting until you find the exact positon, some manufacturers won't even tell you the settings, if this is the case get some-one who is good with engines to set it up.

right, screw the little screw all the way IN till it stops but dont force it.

screw it OUT 2 and a half turns.

Thats about right.

Adjust the idle to the correct levels with the big knob (ooh err)

onthe picture u have shown it says the pilot screw is on the left? is this the screw u turn to adjust the mix? because on my bike its on the right of the bigger screw.

doesnt screwing it in make the gap smaller therefore meaning not enough petrol gets through
