Re: Car won't start without priming carb

That is where a rear mounted electric pump pays for itself. My usual procedure is to run the pump for 10 seconds or so to get gas into the carb. Turn the key off and pump the gas once or twice to set the choke and prime. Turn the key back on and hit the starter. Generally it then fires fairly quickly and once the engine is running turn the electric off. Saves all that cranking and possibly overheating the solenoid and starter.

Starters do not like to be energized for more than a few seconds at a time. On the pinion shift solenoids used with senior starters, heating the solenoid coil can be a real issue. Heat can distort and expand the winding form and cause the plunger to stick in the bore. I have one of the senior Autolite solenoids with that very problem. The coil form distorted so the plunger cannot slide in so solenoid is no longer usable..
