Hard to start when hot ??

Had the same problem w/my 72 Duster. Eddy carb & intake. Notice the old coil was getting very hot (too hot to touch) replaced it with a MSD Blaster 2 and added the Eddy 1/2" wood spacer/insulator plate. Not sure which piece fixed it (guessing the 1/2" plate), perhaps a little of both, but she starts right up no matter how hot it gets now. Easy fix...Just a thought

Good luck getting it sorted,
Pat
