I pulled the manifold off and snapped a bolt off i nthe manifold. Finally got the manifold off. I removed the Rocker assembly and started removign the head.
OH, before i pulled the head I ran a compression test. all were around 65 psi. Didnt right it down, but steadily at 65. Added oil to each cylinder and no change. Anyway pulled the head off and it has the fire crater pistons. They look NEW! The sleeves are as smooth as silk! No movement of the pistons in the sleeves. Remember how I said the block had been brazed on the left side. Well apparently it happened in side too. There is what appears to be a srip of Silver seal from the bolt holes between the 3 & 4 pistons up to the 3 sleeve, across and down passed the 2 sleeve, and down to the bolt holes between the 1 & 2 cylinders. There is a tiny hairline crack right in the middle of the silver seal job.
Im wondering if it was silver sealed, then decked and the decking revealed the sealed crack, which is no problem. OR did it get silver sealed, then crack again? Is it ok? Is it the worlds largest paper weight now? But NO OIL in the water and no water in the oil. Im going to take the head and have it boiled, and have new valves installed, and have new seats put in, new guides the works! There is alot of carbon build up in the combustion chamber. only 1 plug was fouled. Im still perplexed about the Distillate/Gas set up. I have a Zenith carb with a petcock in the bottom in the back (by block) for draining the bowl, it has an adjust ment needle on the front of the carb facing out. And it has an adjustment facing down at an angel on the top. Choke rod goes on carb, near block. Float has 2 seperate bouys. IS it distillate or gas? Intake has rounded/squared runners. But has a box in the middle. Is it distillate or Gas?
