1) Thanks for the advice Robert but the impulse part of the mag seems to be working just fine (and why would it cause a problem at low crank RPMs?). I've tried shifting the timing probably a good +/- 20 degrees all to no avail. As for 'wet' plugs after repeated attempts - no they aren't, but read on...
2) I like you 'back to basics' advice jimg, but I don't think fuel and/or spark are the problem - compression on the other hand...
3) ...seems to be an issue. Much to my surprise the only cylinder that pushes my thumb off the spark plug hole with a lot of force was the one I was most worried about - #2 with the custom-made valve holder! While that gives me confidence that my repair to #2 cylinder was a success, it makes me wonder what's up with the other 2 as the engine was running fine before cylinder #2 swallowed that exhaust valve.
I'm going to try adding a tablespoon of oil to cylinders 1 and 3 to see what happens - if there's no obvious compression change I'll assume the exhaust valves on those 2 aren't sealing properly and then have to figure out what, if anything short of tearing the head off, I can do about it.

We needed a TRACTOR; not a riding mower or tractor wannabe, but a real TRACTOR. The answer to our needs materialized in the form of a '44 Farmall A, complete with cultivators, discs, single plow, a 5ft.Woods belly mower and one, mounted spare 9.00x24 rear wheel.
