Re: Spitting back through carburator
Here's a link to a good article on oils and cam break in. I'm still waiting for my oil which I had to special order since no one carried the Lucas brand locally. As you can see from the article Lucas has the highest concentrations of zinc. Apparently this issue regarding cam lobe wear at break in has been around for a while. Don't know why I missed it. Should be plastered in big letters on billboards across the country.
