I'm noticing that, after shutting off engine for awhile(to run into the store for 10-20mins)AND if the engine temp gauge is reading well toward the hot side(Before Starting),the engine is difficult to start...acts as if it is either flooded or can't get enough fuel initially and slowly ramps up to normal operation. After it has time to cool down, it has no significant problems starting.... Ideas???

Very common issue with our L-Jet systems. Search around here and other Z sites and you'll find lots of people with the same problem. Lots of band aid solutions too as well.

As for whether it's rich or lean? The common belief is that it's running lean.

This is a fairly good thread on the topic, also search on "hard starting" and "hot restart" to find others.
