I think I've found the issue. There is a vacuum leak where the intake
manifold mates to the cylinder head. I had recently had the head off the
engine and apparently didn't get something quite right when I put it all
back together. The only leak I could find was near the front of the engine
affecting the front carburettor.
I plan to remove the intake manifold and replace the manifold gasket. Is
there some special precaution/prep I should follow to ensure success?
Thanks for your help.
