carb problems?

Yes, a good cleaning, and a new accelerator pump will come with the rebuild kit. Should only have an inline filter up at the carb, unless something has been added. When you take off the filter, keep it horizontal and dump the gas in it into a clean can or cup. If it is clean, ok, but look for bits of rust or gunk, that might indicate junk is floating around in the gas tank; look for same in float bowl. If suspicious, have a helper turn the starter while you hold a clean can under the gas line and run a quart or so into it. If it isn't clean and spotless, you may want to drop the tank and check it out. But my bet is that carb kit and new accel pump will do it. Had one of those 74s myself, best MoPar I ever owned, all considered. Wish I had it back...
