Re: Hello from modesto.
I looked at the plug color chart on another thread. I have run three tanks through thus far using a 20:1 The Plug was dark and oily. Now I bumped up to a 32:1 (maxima Pro castor 927) and installed a new NGK B6HS plug. I'm about a half a gallon into the new ratio and I still have a really dark oily plug. Will this clear up? Should I bump up the ratio?
P.S. Can I use break cleaner to clean a fouled plug?
