Well, it got me to and from work again...

Interesting observation on the two trips... Morning run and evening run were about 20 degrees diff in air temp (Farenheit) The scoots still not quite right but its not right in two different ways on each trip.
Morning run, cooler and denser air, it idles high when the bystarter is engaged (almost enough to make it creep) and acts like its getting the perfect mix and rarin' to go.. suggesting that its still idling a little lean when warmed up, but at the end of the trip, fully warmed up it really didnt act that way.
Evening run, warmer and less dense so making the mix richer still.. No fast idle, even on first start with the bystarter engaged but its clearly warming up rich unlike the morning. Once its warmed up we're back to "normal" behavior at idle. Nice stable low revs and running even.
Morning run it tended to bog when nailing the throttle from idle, evening run not a trace of it.
Mystic Meg says theres a jumbo box of clean plugs and a lot of chops in my future.. But you know... This is a midwest spring. Temperatures are changing fast enough that if its this sensitive I'm going to get it dialed in just right and a month later have it all to do again... maybe I just need to find a decent medium-level setting and just get peak performance for two months of the year.
