Okay, an update and memory kicking in. Engine cold, wet compression test: 1 - 80 2 - 115 3 - 110 4 - 115 Plug 1 bad, bad carbon foul. All others really clean.
Engine runs fairly rough - had planned to fine-tune the timing, just in case; but first tried something else. Removed the plug wire from #1 cylinder and felt a bit of a shock to my finger but no change in engine running. When removed other plug wires individually, there was change in engine running. Sooooooooo, #1 cylinder is getting fire; but compression is significantly less than other cylinders and plug is carbon - not oil - fouled.
Also held a wad of white paper towels around valve cover breather/filler cap for several minutes to "catch" some of the smoke or oil. No oil on the towel.
Then, a flashback. After not firing up the tractor for 6 months or so, I fired it up last week before stripping externals for cleaning/painting and - removed plugs. Carbon black on ALL the plugs. Did my thing, then cleaned the plugs, put 'em back in and fired her up yesterday. Probably drove her around 15 - 30 mins yesterday and today. Pulled plugs for compression test and no carbon except on #1.
All this leads me to................?
And, while y'all are pondering whether to respond to this, before tarping her from coming rain, I squirted a liberal amount of PB blaster into #1 cylinder, waited about 5 mins, turned her over a few times with ignition off, squirted more PB Blaster into #1 and tarped her for the night.
Any takers with opinions as to cause of problem and other things I may do in addition to what has already been stated by some??????

Today's Featured Article - Fabrication (Who Me? Make it myself?) - by Chris Pratt. First of all, what are the reasons for not fabricatin your own parts? Most judgements on what should be purchased rather than fabricated stem from: Originality - If the tractor restoration is to be 100% original, it is likely that you should spend the time and money to locate the component in the used or New-old-stock market.
