Spark Plug Wires

One thing I've found that if you run solid wires, replacing the coil to distributor wire with a piece of suppression wire helps a lot with interference. Every spark impulse goes through the suppression wire, but the long runs to the plugs are unimpeded by extra resistance.

Can replacing just the hot wire with a suppression type of wire cause any staring problems like hard starts? Have you ever heard of that?

By "hot wire", are you referring to the coil wire? If so, I haven't had any problems currently. However, the car (a '51) came with a factory coil wire that had a black "thingy", about 1/2" in diameter and 1 1/4" long, in the middle of a couple of pieces of regular solid core spark plug wires. It came on the car when I got it and the car was very original. The car started to run badly after a couple of years, and replacing that funny coil wire fixed it. I figured it was a factory suppression device that had gone bad; which is where I got the idea of using a piece of suppression wire as a replacement, that seems to have worked. Dissecting the black "thingy" without destroying it proved to be impossible.

Yes I meant the coil wire. I had head scratching problems with antique Ford radio that had been converted to an Aurora digital radio, bluetooth, USB, AM, FM with running non-supression wires but not with the radio signal, with the modern features of it playing songs from your iPhones library it would skip songs like crazy, even off a USB plug in it would skip the songs to the next so fast all you could hear was a jumble of snippets of sounds. Switching all wires to suppression cured it as did keeping the old style solid core wires and just replacing with one suppression wire on the coil wire but also tying that suppression wire in a figure eight loop as they show in the directions from the radio kit. It was a frustrating but interesting learning experience. Then recently someone told me that using suppression wire on proper 6v systems was a no-no and that it could cause starting issues. Like hard starts when engine is warm, almost mimicking of vapor lock. I wonder if anyone has heard of using suppression wire causing starting problems on 6v cars and trucks?
 
It sounds to me that everything was fine until "someone told" you that it "could cause starting issues". It didn't for me, and you seem OK with it, so why listen to "someone"?

No, the engine hot hard starting issue pops up every now and then. The precedent actual problem is the hard starting , not listening to “someone”, lol ..how on earth did you reach that conclusion?
