That’s the way I’ve always done it. That way you know if your spark is good or weak.Guess I'm old school, I keep a new spark plug grounded to the block to check spark.
If you can't see the spark just stick a screwdriver in the boot, grab the screwdriver shaft and crank it, LOL!!Tried and true . Always worked . Problem being most of us can't see the spark anymore..

xcept that clamp really sucks. Week, falls apart, won't hang on
Roger you are one unlucky guy. The fake sparkplugs I bought many years ago from my brother in-law's Simplicity dealership have a clamp on them that will bring tears to your eyes if you get it on your finger. The only bulb that's been thrown away is one I accidently smashed. They are flimsy that way.Those bulb type are useless as every time i wanted to use one the bulb was burned out. Just threw four in the trash the other day.
I got mine from NAPA. Spring kept jumping out, clamp fell apart, etc. Probably sheep china stuff. After I soldered the wire on the clamp area and with clamp on the end it works great. The bulb type - the bulb would turn black as coal so no use even trying it. Cheapies off the internet some place again China knock off.Roger you are one unlucky guy.
