So I drained the gas, refueled with Shell Gold gas and it now seems to be running fine. I hit it with the A/C and the electric water heater for loading, figured that was a pretty decent test.
20 min, only one hiccup - a slight sputter.... Enough to kick the AC power off, so will continue to require monitoring but it sounds a LOT better so far.
Progress? Hope so.
