Lighter = Faster (N/A build thread #2)

Well, I got it started. I think it was a combination of too much fuel and the throttle being too open. I backed off the throttle stop to around 3% (was 5%) and immediately the engine started to catch more and more with each start attempt. When it finally caught it idled around 700 RPM and was running super rich (<11:1). After adjusting the throttle stop and the fuel settings I got it to idle fairly consistently around 1000 RPM. I played with it for over an hour, varying engine speed from <1000 RPM to just over 3000 RPM. I ultimately stalled the engine with what I think was a lean condition. I tried to restart it but after two failed attempts (too lean again?) I had drained the battery. I'll try again tomorrow but I'm thinking I may have to set up some kind of post start enrichment strategy.
