Before solderring use a wet sponge to wipe off the soldering tip then re-tin (melt solder) on the tip for a faster heat transfer to the solderi. Can’t think of it now but there is an insulating liquid in a 4 onze bottel from m g chemicals on the web. Insulates up 3400 volts & looks like clear fingernail polish. Called corona dope, I remembered.
It was designed for flyback transformers in T.V. applications Flybacks make very high voltage for the tv scanning beam & they always arced until corona dope was developed. I’ve coated magneto coils with corona dope but added very fine fiberglass cloth saturated with corona dope for stability. Tom is correct, soldering coils is touchy. need to get in & out with the hot tip very fast & still might ruin the coil, The secondary windings are as thin or thinner than a hair. If you don’t want to pay shipping for new wire for the spark plugs go to a neon shop & ask for G.T.O. wire. stands for gass tube only. It is rated at 15,000 volts & get Hi-Flex wire, it’s made to flex for moving noen signs, All my motors I used gto wire & no problems& costs much less!! .
Good luck!!!
