Peugeot 103 Malossi 70cc, 16mm phbg. I've been running it with the needle set at second from top (second leanest) for a few years and it was always too rich, so I finally put it to the leanest setting and this feels really solid. It's either a w7 or w9, can't remember (I know i should probably mention it, or know but I did this a couple days ago and can't remember). Is it ABSOLUTELY out of the question to set the needle at the leanest setting? When I'm 'riding the needle' it doesn't feel totally lean and when I pull the choke a tiny bit it will 4-stroke, so i'm not terribly far from the 4-stroke point. Thing is, when I shift it down to the second leanest spot, it 4 strokes like mad in the needle, takes forever to hit the power band and you're screwed on a hill. At the leanest setting it's fine.
