I'm going to play with them again and see if I can get them right. The choke thing had me worried too, 7-8 tries I'd guess yesterday to light it, which probably drained the Shorai enought that 15 minutes later it was dead. If it wasn't so hard to start maybe the battery would have gotten me home?
Do you recall where you had the floats set? When you set the slides did you use a feeler guage or tiny drill bit? I doubt I can do much worse than H2W's JD jet kit mix. Did you happen to post up your settings or a process of how you dialed them in?
