Plymouthy Adams Posted May 15, 2021 Report Posted May 15, 2021 when I was a younger person my grandfather had a HUGE old spark plug, massive honker with a propeller on the electrode.....I asked my cousin about this a minute ago and he also does not know who got that when grandpa passed. He did remember the plug however.....I tried to find a picture of one...came up empty handed....anyone ever see a plug of this sort? Quote
cheesy Posted May 15, 2021 Report Posted May 15, 2021 I used to collect old spark plugs in the 60s and that one doesn't ring a bell. Quote
Plymouthy Adams Posted May 15, 2021 Author Report Posted May 15, 2021 I had only seen the one myself....all I can say this is what I recall as does my cousin and brother.....I bet the base was a good 1 1/4 inches..but then as child many things are bigger than life... Quote
Sniper Posted May 16, 2021 Report Posted May 16, 2021 Wonder if it was some sort of aviation plug promo? Was he into the aviation industry at all? Quote
Plymouthy Adams Posted May 16, 2021 Author Report Posted May 16, 2021 (edited) no...he was listed as a distiller....worked for years in the production of gas...we talking starting out pre-1920 in the business... I had sent my cousin a request for a picture as I was sure he would have had that.... Edited May 16, 2021 by Plymouthy Adams Quote

Plymouthy Adams Posted May 16, 2021 Author Report Posted May 16, 2021 excellent....you my hero.....lol I know a lot of folks was saying I had one too many cups of coffee today....wonder the speed of that fan on compression stroke.... Quote
Tooljunkie Posted May 16, 2021 Report Posted May 16, 2021 That is the coolest spark plug on the planet! Quote
chrysler1941 Posted May 16, 2021 Report Posted May 16, 2021 Very cool but hopeless. ? What's the purpose? Better fuel mix? Better complete flame combustion? Once saw an old Lodge spark plug with pink insulator. It had a tapered electrode. Nothing to adjust. Later re-invented by NGK Quote
Plymouthy Adams Posted May 16, 2021 Author Report Posted May 16, 2021 we talking early developments here...to this day folks still playing with multi-tip spark plugs....this is just that young pup's granddaddy Quote
