MGB MGB Won't Restart When Warmed Up!

Thanks to everyone for all the input.
I've been out of the country for the last three weeks and only arrived back home late last night.
Just before I left I had time to purchase and install a cheap regulator on my 'B'. I dialed the pressure down from ~4.5psi to 2psi. A 1.5psi setting on the cheap regulator turned out to be ~2psi of real pressure.
With limited testing time before I left, it seemed that the reduced pressure was the key to most of my problems(no more leakage or extremely rich conditions on restart of a warm engine)
Before I left on my trip, I ordered a new EGR valve and the ColorTune kit. Both arrived while I was gone. I plan on installing the EGR and then adjusting the mixture with the ColorTune and seeing what happens from there.
