:usflag:View attachment 1715531167 Good evening everyone. This is my first post. Anyone familiar with the 66 Dart GT 273 and had intermittent idling and backfires. It doesn't matter where the timing is set. So heres the backstory. Bought it. Not running. Heres the new items. Fuel tank, coil, plugs, Holley 4160 carb, blue streak cap and rotor, wires are coming tomorrow, she starts and runs now. But its weird. At idle let's say at 1K she idles down then up then backfires then up back down again. I'm getting enough fuel. Bought a new carb just to make sure. Checked fuel pressure. It's good. Could it just be a faulty distributor? Everything else is changed except for the Distributor, wires and ballast resistor. New wires and distributor coming tomorrow. Thanks for reading. And I'm glad to be part of the site.
