ON our RC model plane engines that size plug is quite common, and we use the RCEXL ignition systems to fire them. A replacement spark plug boot can be had from any reputable RC hobby shop such as Valley View or just Google a search for 1/4" -32 spark plug replacement boot and you should be good to go..Here is a bit of an odd question. I am using a 1/4"-32 sparkplug in this engine. The end which the wire attaches to is 0.160" diameter x +/-0.075" long. Does anyone know of a sparkplug boot that fits over this size of sparkplug or is it a flat/split wire terminator that snaps over the reduced area in the center of the sparkplug terminal?
I don't know you well enough to know yhour habits, but as we are all "getting up there" we should take as much precaution as we can for our health. My wife was on concrete floors for 25 years--she got arthritis in both knees. So my advice is, if you can, always have a stool in your shop on which to sit for any operations that you are doing, that you can. I use a stool even when machining, as so many operations are semi-automated, that is, you have to watch in order to stop the machine when it's operation is over but till then you can sit and watch.
Glad to hear it went well!
