Oh great Happy-Time gurus lend me your wisdom.
What's a good starting point for throttle needle valve for the first start and the break-in period? I'm finally about to get my Zoom 80/66cc going for the first time and want to minimize the initial hassles. My needle valve has the 5 grooves and the circlip is on the middle one straight from the factory. Obviously since that little valve has a lot to do with the leanness/richness of the mixture I'd rather have it a bit on the rich side for the break-in so I'd rather lift the valve a spot rather than dropping it a spot. Else, leave it in the middle as it is.
