Talking 1970 Hydro 147 Engine Overhaul

Well it's that time of year, I've had the Cubby for just a few months as the free John Deere finally passed away. I'm excited to have such a great looking classic tractor although everyone keeps asking me why I'd buy such an old thing instead of getting something new. To me new=crappy low quality stuff you'll just end up throwing away in 5 years. So I've just pulled the K321 for a rebuild. My question is are there any sneaky details I should be aware of when doing the rebuild? The cylingder walls look ok, nice and shiny, I've yet to put the calipers on it to see what it measures. It was blowing smoke, and I see by removing the head that there's a source of oil, seemingly from the intake valve, which I assume can be remedied with some new valve seals. I found a good kit on eBay for $80 that has all gaskets, piston, rings and oil seals, so I should be good on that and there are various sources for the carb rebuild. Looking forward to a winter in the basement scrubbing 30+ years of oil and gunk out of the thing and get it back to business in the spring. So any good tips and wisdom are appreciated, thanks again ! I'm new to the Cub scene, but got sucked in right away when the 147 came off the trailer !
