Re: What you think of my plugs?
They look fine for heat range , I do see some pre ignition fouling but nothing timing wouldn't fix and maybe better gas.
The first picture show a loose plug, the brownish ring around the gasket. 3&4 show a slight oil burn, maybe guides, you can test that with a vacuum gauge. 4&5 slightly white but can be due to pre ignition
