I threw away one spark plug because the side electrodes were becoming thin. heat treated some of my old copper gaskets. when they turn black, they are done.

Old buzz box works on a 9-volt battery
I purchased this old buzz box 10 years ago for $20 on eBay and limped it along with tape around the battery set, but it is now too far gone. luckily it works on a 9-volt battery. I haven't needed to time these mags for past 200 hours. but they need it now. they have both advanced 2 degrees, and I can determine that from the uniform CHT creep. at altitude I can run LOP and drop them to CHT 315F range with 2 degrees advanced. I'm OK with the creep on these mags, minimal effort for timing them.
