Re: 1930's?
Questions are fine. I'm happy to help with a classic, such as this
I would still run it at 24:1, reguardless of the new kind of oils of the current times. It will only be better for your engine.
As far as the water pump. Keep a feel of the heads and make sure they don't get hot while you're running it. If it's a piston pump, then I would spray it down with WD-40, before you crank it over and get it working nice and free. Pull the spark plugs, before you do this and spray a bunch in the cylinders too. Crank it over several times to get it all worked inside of it. After you do that, then lay it on it's back and dump about a cup of fuel mix into the carb and spin it over
slowly. That will get the crank and rods all nice and lubed up and spinning free again. The lower unit may need to be recharged with fresh grease again. I like to use the white grease (Lubri-Plate 105 Lower unit Grease) for gear cases like that.
You might want to pull the flywheel and clean and lube the points good. Set the points at .020 and check and make sure you have good spark.
By now, your motor may be ready to fire, once you put fresh fuel mix in the tank
Let us know what happens.
