It worked, kinda. She doesn't share in my affliction so even though she accepted my offering, we ended up parking El Blanco for three years.
After using my other two Cubs to prepare our 1/4 acre garden this year, it became painfully obvious they both need some TLC.
So, I decided to pull 'ol Blanco out of her 3 year hibernation and determine her overall health. 6 volt generator with cutout, 4 position light switch and magneto. Brand new aftermarket $45 carb.
Removed the hood, attached a pony tank, primed the oil pump, and pulled the starter. To my surprise, she fired up after the second try, with half choke. Allowed the engine to warm up and drove it around for 30-45 minutes. Smoked pretty bad for first 15 minutes and then subsided to this,

Only tractor I own that keeps high oil pressure when hot.

Turned off engine shortly after the video and pulled the plugs. 4,3,2,1 in the photo.
#3 was oil fouled and the others have significant soot on them. The plugs are Autolite 386. I purchased some 3116's to replace them.
I poured 5-6 ml of seafoam into each cylinder making sure the valve and cylinder heads got a good soaking. Allowed to sit for 24 hours now.
Question 1: Should I use the old plugs when firing back up to rid the seafoam, and soot hopefully, or go ahead and use the new 3116's.
