I new something wasn't right, and so I took the head off again and noticed some leaking had definitely occurred between cylinder 3 and 4. This didn't even happen before when I put it together again. What I did notice now though was that If I tried to throttle it up at all, it would instantly die. I now am finally getting back into it, and with fresh gas I went to start, and after more coaxing it came to life, however with the white smoke still present. Other circumstances came up, and I had to put the project on pause. Upon bringing it back into the shed, I also noticed a bead of coolant had formed around the left side of the head between the head and block. When I went to start it after the tuneup, it took a little coaxing but finally started. Adjusted those to the correct specs as well and installed a new head gasket of course. I also inspected the valve clearances and discovered they were way out of spec. Valves on the other hand had a lot of build up, so I cleaned them and the seats up properly, and was fortunate to not find any pitting. Cylinders looked to be in excellent condition, and only minor carbon buildup on pistons. I decided to removed the head to inspect the cylinders and valves. By the time I got to working on it, it was winter so I had more time on my hands. It came with a belly mower, and I noticed it was struggling more so than a Cub normally should. Last year I acquired a second Cub from a family friend for next to nothing (oddly the same year as my first, 1953).
