Curt,
Thanks for the info...
Now another question. After about a 5 year sleep, mostly outside and unattended, I drained all the fluids in the engine and refilled with fresh. I noticed radiator fluid leaking slowly out of the block, beneath the manifolds, around the throttle linkage...
I assumed a cracked block, but when I pulled the head and manifolds off and scrapped away 50 years worth of gunk, I see no crack...
Any idea what the problem and remedy would be?
Planning on rebuilding the engine and would hate to go through all the trouble and expense and end up with the same problem.
Thanks
