Holley has pump diaphragms that are ethanol fuel compatible, they are green colored. I don't think they come in any kits but can be bought separately..

I had the carb. professionally rebuilt and the engine now runs great.  The rebuilder told me that the choke was stuck because it was full of exhaust debris that entered the choke through the pre-heater tube.  He cleaned it out and freed up the choke.  This carb. is on a stock intake of the type where the pre-heater tube connects to the center leg of the intake manifold not the exhaust manifold.  With the tube disconnected and the engine running I can feel exhaust gas coming out of the threaded brass fitting on the intake.  What could cause exhaust to enter the tube and how can this be fixed?   I am toying with the idea of just converting the carb. to an electric choke and capping the fitting on the intake  but I am running a 6 volt system so I don't know if there will be enough power to run the choke element.

There is a thin sheet metal tube that runs the horizontal length of the intake, from side to side. After almost 60 years these things are usually toast. Different restoration companies sell replacements. You will have to pull the intake and use a punch to drive out the old tube and install the new one - they are a press fit.

Thanks Daniel.  For now I just opened up the choke fully as the weather is getting warmer here in CA so I shouldn't have any problem starting the car.  When things get cooler in the fall maybe I will be in the mood to pull the intake and repair the tube!
