53 3100 with a rebuilt 235. Manual choke, electronic ignition, Rochester 1 bbl carb. When starting cold it idles and runs like new. I can drive it about 10 miles and it will not idle. Just like you turned the key off at an intersection. It will instantly start up and run after that, but will not idle. I can let it cool down @ 10 minutes and it will idle fine. Any ideas? Thanks
