Getting my 31 to run right.

[1crosscut]

Your making good progress. Water coming out from the cap is not necessarily an indication of over heating but of a poor seal on the radiator cap and possibly over filling. If over heating the coolant should be pushed out of the overflow tube not the cap. Easy to check to see if the overflow tube is plugged.
Coolant can be pushed out of the radiator under load if a head gasket is leaking.
Best way to be absolutely sure what the temperature of the coolant is to get a dial meat thermometer and place it directly into the top of the radiator into the coolant. Maybe it is just me but having one in your Model A tool bag is a must.
Lots of folks use the laser thermometers to read temps. They are okay but useless if the battery runs out.
