In order to start the car you need fuel, compression and spark. You say that the car runs fine once it is started, so I would start by looking at the fuel system. There are 2 conditions that the fuel system can have to cause hard starting. lack of fuel or too much fuel. The lack of fuel condition occurs most often after the car has sat for a few days or longer. It can be caused by a leaking carburetor. You would have to identify the carburetor model in order to check this out as the Stromberg carburetor has different causes than the Holley / Ford carburetor. Please post photos of the left and right sides of your carburetor. This will help in diagnosing your starting problems. You also said that you replaced the spark plugs. Did you check them for signs of running rich or lean? Use this chart if you still have the plugs: http://www.verrill.com/moto/sellingguide/sparkplugs/plugcolorchart.htm The condition of spark plugs can tell a lot about the engine, carburetor and ignition systems.

Hi Tom, I think that I agree with you. It may be the Carb. I am getting a strong spark. It is the original coil. I removed a plug. It seems to be burning rich. (see photos) I do have another carb that I had from my previous 36. I may try switching the carbs.

It looks like you have a 24 stud engine (1939-1948) in your car and a model 59 carburetor. The spark plug shows a very rich condition and you probably should have the carburetor rebuilt by someone who has lots of experience with these carburetors like Charlie Schwendler in NY. He does a good job and machines the power valve seat so that it doesn't leak. All of his carburetors are engine tested before shipping. His E-mail is cas5845@yahoo.com His phone number is 716/662-9159. If you do decide to rebuild it yourself, Daytona Parts has the best kits, but their float valve adjustment is very finiky and difficult to get right. Your spare carburetor is for the 49-51 engines and it looks like it had a leaking problem also.

Thank you everyone for your advice. I did replace the carb with the spare one that I ha. The engine started right up!! I will send the older carb to be rebuilt by Charlie.
