Just a comment from one of the "old guard", I have noticed over the years that virtually EVERY mopar
I owned or knew of took a slightly different starting technique.The were (mostly)all very unique.
Some want the "pump like hell" deal, some you pump twice to the floor, then crack the throttle about 1/4 way and hit the key.
Some you do not pump at all, don't even LOOK at the gas pedal.If you pump, you flood, and you have to wait a half hour and try again.
I agree 100% that the Dart has some possible issues with ignition.Just sayin' it sometimes took me awhile to get exactly what that particular combo wante to start easy.
