OK. I own a 76 cj-7 with a 304...INITIAL problems-engine dies without warning, may sputter then get better. Changed entire (module, coil, distributor -rmfg-, cables, plugs) ignition minus timing gear. That cured the lack of spark. Next problem. starts doing the same with exept black smoke and backfiring. Cure? new fuel delivery system (rmfg carb, fuel filter). Now that it doesnt die when it feels like it, it bogs down when I shift from 2nd - 3rd and 3rd till i get up to speed. My jeep does not have a tach and have tried to adjust mixture on the motorcraft 2150 carb (76 era)and changed the throttle cable to the 2nd hole. it seems to level out when the jeep gets to a good running temp but from cold to warm it sputters until the rpm's pick up. anybody have a similar problem?
