Mopar misfire on idle

[1974dodgecharger]

Is it really the common occurance on the misfire especially on start up due to low rpms?  I get it on occasion and it forces my car to back fire unless I sit there and let it warm up for 3mins even when hot first start days here in Phoenix when it can get to 110 plus.  If I start my car and don't let it warm up and put in gear and get going I get a misfire and backfire through carb, but after a warm up everything is fine and dandy. 

Saw this on ebay by Richard saying his reclutor will cure the misfire.

that is a common problem and that is the reluctor to use to correct the rotor phasing on a stock mopar dist.

well worth the effort to set the dist up correctly.
