It reads like you took the ribbing in the right way. I couldn't resist. (We Talers have to be careful when we venture onto serious boards!)
On more serious issues, you're saying advance, which is BTDC, B for before. A(fter)TDC retards, but it's clear you're thinking in the right direction.
Yes, by rights, on a tight engine, static timing should give you the right advance at speed if the advance mechanism is working correctly.
But as James Pumpf points out, you'll get slop in the timing train with wear. This occurs primarily between the crank and cam gears, and cam and governor/distributor drive gears. That will cause the advance mark I described in the post above (q.v.) to float but stay in visible range. Because small turns made with the fan blade act on the crank gear, they won't show up by resistance, but you can sometimes detect that kind of slop with some clicking/clacking sounds as you rock the fan back and forth.
If you're able to mark off the 40 degree advance mark and find yourself in the ballpark on running timing, though, I'd address other possible, electrical weaknesses in the system first, but you can't eliminate the possibility of worn shafts in the distributor. IH put plugs instead of zerks on the lube points for them, because they don't need much grease or often, and I guess there were problems with folks not reading the book and pumping a grease gun on zerks until grease came out somewhere, at which point they had pumped the distributor body full of grease (not good). The payback is that with the plugs, a lot of them never got lubed and have worn until they are out of round, which would cause your timing light, at running speed to skip, as opposed to the mark just floating a little.

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac.
