I just got my two points type distributors for my twin 165's that have HEI's on now, one has the familiar screens on the bottom, one does not, other than that they are identical, did the early ones have no screens??
Thanks
Ayuh,... It's the metal screen that stops sparks,...
Could it have been lost over time,..??
No, there are no holes in the bottom of the housing for screens, it is solid. There is no provision for a vacuum advance either, so I's not automotive. I'll post pics when I get home.
Thanks
Ayuh,... Donno if it applies or not, but some of 'em had a brass elbow in the cap,...
Sparks can't travel 'round metal corners either,...
Distributor, Has to be vented, somehow, somewhere,...
