It probably wasn't timed quite right but Dad and I got the 80 to start and idle for the duration of a couple of full carb bowls (manual specs claim a GT 80 will get 178 MPG so we're talking a couple minutes). I gotta admit, I was even more psyched to hear it run than I expected to be. Every time I work on something with Dad I'm pretty much floored by the stuff he knows... He's pretty damn good.
Next task on my list, clean out the gas tank. I started with a couple of rounds of Simple Green and a handful or 5/16' nuts. That worked pretty darn well for the heavy crud. 4 or 5 more hours of shaking and I think it would look like new inside. Mostly just rust left. I got lazy and decided to try electrolysis. It seems like it's really working pretty well so far. I figured I'd post a picture just cuz it goes so well with the post caption.
