<VV> Engine with no compression

[corvairduval at cox.net]

When you tried starting the engine after its 4 year sleep, did you just
crank it with the four year old gasoline in the system?

If so, I would drain the gasoline from everything. Refill with newer
gasoline. Take off the valve covers and see which intake valves are stuck.
Apply liberal amounts of carb cleaner and lubricant (carb cleaner to remove
the sticky from the stems, lubrication to allow the stems to move again).
You may have to use a hammer and other tools to move the stems to start.

This happened once to me when I tried to burn old gasoline from a sleeping
cutomer car in the shop Corvan to get rid of it. Mix ratio was too high,
probably 4 parts old to one part existing in the tank (shop van never had
too much gas...). Stuck all three intakes on one side. A little work and we
were driving it again.

I have a '67 110hp automatic which I had running very well 4 years ago. 
Employment changes took me away, so the car was stored under a tarp.  The
other week I unwrapped it and tired to start it.  It has spark, and I
have been dribbling gas into the carbs with no fire from the engine.  It
turns over very rapidly as if it has no compression.  I have already
tried squirting oil into several of the cylinders in an attempt to get
enough compression so that it might at least start on those cylinders.

Is the next step filling the crankcase with Marvel Mystery Oil or
something like that?

This car is 150 miles away, and I'll be able to work on it a bit this
weekend.
