Re: Automat Spark Plugs
Yes, they are a "gimick" type plug with a spring loaded top that supposedly drew fresh air in on the intake stroke. They probably didn't work too well. I can imagine there was a problem with them sealing properly on the compression stroke. Several quantities of them have turned up over they years and they are popular among spark plug collectors (like me). I'd be interested in acquiring a nice one if you have one available. You can email me if you wish at terryaaca@cox.net
