I have a 59 371 with a Rochester 2 GC carb. I think I am having a carb heating problem. After idling for an extended period the engine quits and won’t restart until it cools down. Temp gage hits 180 which isn’t that over heating. I get no indication of over heating, just thinking the carb bowl may be getting too hot ??. There appears to be a thin spacer (1/8 inch) in place now, wondering if a thicker one would help? Any idea where to find one? With a vacuum port ?
thanks for any help you can provide I really appreciate it

180 is normal operating temp. Could you have something electrical, like a coil or condenser that malfunctions when it gets hot ? You maybe could think about a carb "insulator" not a "spacer".
Others will chime in with their thoughts.

Hi

hmm never thought electrical. Will look at that.

I run a insulator on my 55(4gc) and it helps with vapor lock which is a carb heating issue and it helps a lot. Have you tried insulating the gas line from the fuel pump to the carb? If that works there are things that may help that won't be so obvious like a spacer or insulate the gas line from the tank to the fuel pump where it will be hidden if you show your car....Tedd

Hi Tedd

Thanks for the input and I just ordered an insulating sleeve for the fuel line . Also replacing the coil, it’s quite old so maybe breaking down. An insulating spacer is also in the works. I am going to fix this frustrating problem.

thanks again greatly appreciate the input.

Just after the engine stops running, try to determine if it's lacking fuel or ignition. That will somewhat narrow the field.

This^^^^^^, troubleshoot before throwing money at a problem.

When it first dies look down into the carb while operating the throttle and see if you have 2 strong jets of fuel spraying. If you do it's not fuel related.

Hi all
thanks for the help. The coil was breaking down. Replaced it and running better. Still a few gremlins but making progress.
