Classic/Antique Car Repair: 1940 plymouth start up, propane torch, metering valve

Question
I have purchased a 1940 up-10 deluxe sedan and know that the car has not been started in 18 + years what would you recommend as the best starting point to get the car running it is a complete unmodified car and should I use a 12 volt battery to get it going and any other tips to get started

Answer
My routine for these Rip Van Winkle cars is as follows provided that the engine will turn over and is not stuck:
1. Change the oil and filter if equipped.
2. Remove the spark plugs and pour about a teaspoon full of oil in each cylinder.
3. Install new spark plugs.
4. Remove the distributor and install new points, condenser , and rotor.
5. Inspect and replace as needed distributor cap and wires.
6. Install outside fuel source.
7. Install a correct fully charged battery. In this case a 6 volt.
8. I prime the fuel system with a propane torch. That is a torch with the burner head removed and the metering valve removed but the control valve and stem left on. Hold the open end of the tube in the carburetor inlet and open the valve when cranking the engine. As the carburetor fills and fuel is available you should be able to turn the propane off.
9. Run the engine long enough to get the oil pressure up and then shut it down. After you make sure that it runs on all cylinders then service the fan belt, cooling system, and anything else.
Good Luck
