Unburnt fuel/oil coming out of the engine probably.
An engine taking a little oil usually burns it now it just spits it out.

I checked the timing this morning and found the timing not advancing. If I connect the distributor to the wiper motor vacuum port on the carburetor the advance works correctly. Vacuum at this port is about 18 in's and at the distributor vacuum port is about 5 in's and goes up to 10 in's when revved up. Does this indicate a sticky vacuum advance in distributor or something else?

I know there is a spring adjustment in the distributor, could this be the problem?

Its not as simple as a leak in the diaphragm and at the restricted flow it doesnt work and with a higher direct vacuum it moves ?
