The lacquer coated solid core wires are still offered by one of the more popular vendors, minus the plug caps, for Stovebolt engines. I got a set hoping that they would be a little longer. No dice...so I've got some more dust collectors for my "almost treasures" shelf.
I've also heard something about interference problems with blasting....will keep an eye in the rearview to see if I'm spreading mayhem across the land!!!!! Have a friend with a pacemaker....may give him a test ride!!!! NOT!
Think maybe that the spiral wound wires, or for that matter the conventional carbon core wires, require a little more delicate handling. Pulling on the insulator can create small gaps in the core material...the spiral helps prevent that from occuring.
Regardless, I'm happy with the end result and for the smaller out-of-pocket expense. I think I'm getting more "bang" for my buck. Time will tell!!
