Thanks Montesa, dadgum that photo is almost flattering. Yep, we were trying to balance carbs but I still have some rebuilding/refitment to perform. It's amazing that the little guy even ran at all. I don't have a lot of saddle time on the bike but it seemed very rough and underpowered. Imagine my surprise when I discovered that the PO had installed the throttle cable to the choke and the choke cable to the throttle!!! Sorted that out very quickly and now it's quite a pleasure to ride. Still needs a bunch of work though to be up to speed.
