When I recently aquired my D, I found a whole list of things that needed changed or replaced. I changed the plug wires, cap and rotor , found several split vacuum hoses, the O ring under the fuel distributor was shot, the plugs were gapped at .040 and a lot of other things that i suspect contributed to the rough idle. The two Idle adjustment screws were opened up most of the way. Now that these things have been replaced/repaired. I can't get the thing to stay running. When you turn the key, It fires up and as soon as it settles down to idle it dies or if it does run, runs rough and dies if you step on the throttle. It ran in spite of all the things that were wrong before, now it won't run. Any Ideas???
