Not yet undead

Ok, added a gallon of gas, full charge on battery, reconnected the cut AFM wire. Cranked it over and it ran better for a hair longer, long enough to hear the awful clanking noises from then engine. Sounds like the bottom end of this engine is toast. My thought are bearing(s) have gone. The top end is working enough to get compression and to run, but the bearings are toast and causing grindage on the crank where it doesn’t want to turn. I’m not sure why it dies when I try to give it throttle though. I suppose to confirm I should pop the spark plugs and try turning the crank by hand to feel it.
