I am struggling to find spark plugs for my 73 duster 225. I am wondering what spark plugs to use
i have autolite 985 which is recommended by another member. what are drool tubes?NGK 6578 (BPR4ES) is a good one. Just remember, that head should have drool tubes. If it does, you need to remove the metal gaskets from the spark plugs, as the drool tubes act as the seal.

I dont have those on mine, just seems to be a tight fit with the larger diameter plug.They are thin aluminum tubes that the spark plugs install into in the cylinder head. They seal the crankcase from both ends of the spark plug.

I think they are newer heads, but unsure of what plugs to use!Ok, cool. It appears not to have drool tubes.
