My '72 Newport Custom Sedan had a perpetual problem of plug fouling. This has subsided with a timing chain replacement, after the original nylon coated cam gear disintegrated. My plugs stay clean now, and I don't have to punch the throttle to the floor to get enough manifold vacuum to take the choke off of high idle with the new timing chain/cam gear. I wish I would have done this job earlier, it was easy if a little time consuming to do.

I never had a problem with any particular brand of plug. I did have plug trouble if the engine was not driven enough or worn out, the choke was sticky or stuck closed, or I left them in too long. None of those things were the fault of the plug. Paul
