Aligned the Magneto Pulley to the correct mark, (thank you for posting the pictures/instructions!), and re-adjusted the linkage and re-set the timing to the angle on side of block. Running much better, see video. I idled down as low as possible and in and out of forward and reverse. Took break then went back to start and had some issues getting it to start. After a few minutes was able to start again. I decided to pull plug caps while runnig and noticed no change in performance when I pulled clyinder number 4. I ran a spark gap testers and could see a spark but it looked intermitient. Also compared to other cylinders which all did not have any intermittent spark at the same distance of the tool as Cylinder 4.. I pulled the distributer cap and cleaned the terminals/rotor end with 600 Grit sand paper, (very lightly). I tried to swap out the wires but could not figure out how to remove the wires from the distributor, (did not want to brute force). Retested and same results - when removing cylinder 4 spark plug cap while running seems like no change. Went back and re-tested compression. Results. #4 62 PSI, #2 70 PSI, #3 70 PSI, #1 72 PSI. Wondering if Cylinder 4 was lower because it was not firing as much and thus did not get as hot. Will re-test when cold. Are these numbers too low on compression? Thinking perhaps this motor may be ready to send to pasture and start looking for a replacement. Thank you for all the good info/time/advise!
