What is the standard factory setting for needle position for 31K YPVS carbs? I have a spare set of slides and needles, but can't get the screws out of the needle holder on my other set (all chewed up} to see what position the clip is in.

Hi I'm pretty sure the clip should be in the middle, having said that my clip is one up from the middle that is where mine runs best.

Cheers chaps. From everything I've read 31K needle position is 4th from top, as stasky says.
