read my plugs- please
Morning,
I have #5 & #6 getting packed with light tan colored deposits that completely coat the insulator. They look like bubbly white/tan scabs. My other plugs all look light tan / grey and no deposits. This happens about every two months and I have to change them.
I 'll have pics of my #5 & #6 plugs online soon but what do you think is causing this?
76 350, rebuilt 5K ago, 2101 edelbrock intake, 600 edelbrock carb on insulated spacer, hedman headers, msd diz, no vac advance since plug change, all mechanical for now & running better. Previous months, vac & mech.
Thanks in advance for comments.
