Transmission ground strap frame bolt not fully torqued, also red wire from battery only hand tight. Turns over just great, but now floods (with no accelerator pedal use at all) and still doesn’t start!

There were throttle mechanism and vac line issues when I picked it up from Zoltan, will look at that in the morning. It did drive at tbe time. Aside from the stalling under high load, which could have been either fuel starvation, or possibly the tired battery I just replaced.
