It is a pain in the rear to be priming the carb all the time if your vehicle sits for a couple of days. I have three Mopars (with carbs) and some day I am going to go electric on all of 'em so they start when I turn the key. I would suggest everyone else do the same.
Sounds like you have some other problem. Mechanical pump with a Holley on mine and I rarely ever have to crank it for more than three seconds even if I have not started it in a month.
