Up for auction is a 7/8” thread, New Old Stock, CHAMPION TOLEDO PRIMING PLUG spark plug. ** PLEASE NOTE that I am not sure if the porcelain is the original one that came with plug.

*This type of plug with a petcock screwed into the base would serve as a way to introduce gasoline into the combustion chamber to help start vehicles on cold days and also provide a temporary “compression release” when either cranking over a hand cranked vehicle i.e. (Ford Model T) or a kick start on an old motorcycle.

**Please note that I always combine shipping costs on multiple items won. Please do not pay invoice until I adjust to the appropriate cost. Thanks for your bidding.**
