I did set points and greased distributor. I did not grease the shaft.
I'm going to pull the distributor and check the shaft and such before rebuilding it or a new type. Definately has a slight miss. I owned a 30 4 door in the past, so I'm aware how well it should run. I've already rebuilt the steering box and adjusted brakes. Greased almost everything. It's much better but I want this thing to run like it should.

I would try the 20w-50 High Detergent Oil and the Marvel in your gas.
The miss firing could very well be several sticking valves. That might also be a big part of the sounds your hearing.
The heavier oil will also help if the engine has some mileage on it. I think 30 weight oil is to light for summer use.
