Hello Fleetwin,
Here are the history of what I have done.
1) The ignition resolved with great learning about low tension ignition! Complete brand new all the ignition parts.
2) Ran OK with the original carb without the lower unit installed.
3) Ran in the barrel and found the water came out of the bottom cylinder head. Removed the cylinder head and installed the plug.
4) It was hard to start and tried to adjust the carb, Cleaned the carb again and it ran a couple times but when shut it off, it would not run!
5) Decided to buy a better condition carb and ran it as shown in the last video.
Answer specific questions:
– When you removed your cylinder head to hone the cylinders, did you replace the cylinder head gasket or did your reuse the old one? The block completed torn apart and honed the cylinders, clean up carbon on the piston grooves. I reused the gasket!
– Prior to putting the cylinder head back did you clean and true the mating surfaces with sandpaper in a figure 8 pattern? NO but I clean up the gasket, head and block surface with emery cloth.
– Did you torque the cylinder head bolts 96 to 120. I found the information form Iboat forum for the torque spec and I did but I forgot the number. The problem that I could not torque 2 bolt at the bottom of the cylinder since there was no room to get the torque gun there so I tried my best with the wrench! Otherwise I have to remove the block out. In your experience, is there any way to torque these bolt without remove the block? I did two pass, 6 ft.lb and then final torque value with the head torque sequence.
I attach the spark plug picture of the motor. The one on the left side is the bottom cylinder plug. I did not see the droplet on the spark plug.
