First - How about some more details -- What kind of engine, and intake setup are you using?

I don't think changing the mixture is going to produce enough extra torque to rev the engine up to 4500 RPM. That would be extra air, like an idle control valve, or perhaps some post start advance. But my money's on something like a stepper motor idle control that is driven to the stop in one direction before idle control is started.

Look for any idle control settings.

The post start enrichment is part of the cold/warm start cycle which is explained in the webinar. It does sound more like extra air flow causing the high RPM as that is more than you'll achieve with extra fuel and timing from the start up cycles.

Like David has mentioned, look into your idle control valve setting and see what's going on when it's idling high
