Hi all. New to the forum. I've recently acquired a 55 T-bird. All stock except 12 volt conversion. I have very little to no experience with y-blocks. Have to pump the living day lights out on the throttle to get car to start when cold, but starts and runs OK. I know I need to do a tune up but that's got to wait until I get the hot cranking problem solved. After the engine runs for about 10 minutes or so it won't crank after shutting it down. Even if I only wait a minute it's the same thing. Once it's sat for 20 minutes or so it will crank and starts pretty easily. Checked the battery and getting a full charge. I've noticed the temp gauge barely comes up from the cold position. Upper radiator hose doesn't get hot to the touch which is making me think the thermostat is sticking. Maybe the engine's getting so hot it won't start? I don't want to just start throwing thing at the problem. Thoughts on my diagnosis? Other things to look at? I'm not a great mechanic but really good at following directions. Thanks in advance for the help. I'm also posting this over in the technical section.

First check all the electric connections to the starter. But this really sounds like a over heated/worn out starter issue. Rebuilding should cure it. The pump issue is carb related, usually you'll find the fuel is draining rom the carb bowl when it sits.You have to crank it for the pump to refill the carb, and the accel pump is probably not up to snuff. Does the choke work?

Choke at this point isn't working.  THere's a carb rebuild in the future.  THanks for the ideas.
