Default Re: Cobwebs/black soot & oily plugs

Unfortunately when plugs are fouled from no long hot runs they stay fouled , well my engine guy says you cant satisfactorily clean bad plugs.
Perhaps leave the fouled plugs in Apatchy for your startups and replace with shiny new ones on your next road venture.
