Hello, I have a Faema Faemina which I have recently resealed. During this work I discovered 2 of the 4 ceramic insulators on the electrical terminals where broken which lead me to this idea. I cut the last 2.8mm of old spark plugs which are also made from ceramic (high quality). They are almost a perfect match to the original ones. I hope the photos supplied will inspire others to go down the same path
