Good news, bad news thing. Bad news is that you cant get rid of it completely. Todays fuel loves to boil and gas is no longer blended for carburetion. Good news is an easy fix. Replace your carb base gasket (which you will find is thin paper) with a thicker composite one. Get a base gasket for an 85 Ford truck with a 460. Fixed many and it works quite nice. It stops the boiling in the carb and minimizes the fuel foaming on fire up after it sits in a hot soak. Only issue is what foaming is left after it fires (usually mid 90's out). After it starts you may have to hold the gas down for about 10 seconds for the bowl temp to stabilize. This works well on both the Autolite and Edelbrock carbs. My 65 started like crap at 80 deg and the fix was night and day difference. As far as the anemic crank, make sure somebody didn't jack up the base timing to cure the other problem.
