Re: Unable to start up 1940 356 engine

While I was getting my car running, it flooded badly several times. I tried everything I could think of to get it going, but after getting the fuel pump rebuilt, new ignition parts, etc, and it still wouldn't run, I replaced the spark plugs. She fired right up and ran like a top. It was the first time I had ever seen fuel fouling of spark plugs on a four stroke motor, but it did the trick for mine. I see you have new plugs, but if you have done much troubleshooting since replacing them, they could be the problem. I am sure you have already tried this, but if not, you can verify spark by pulling a plug and setting in on the exhaust manifold or head while cranking the motor.

Also, make sure your starter cables are big enough- if not, the engine will crank over much more slowly than in needs to. I put a 2 (00? - it is about 1/2" in diamater) gauge ground wire on my car, and it started much more easily.

Best of luck, and let us know what you find.
