Judging by my experience the effect of the catalyser begins to decrease noticeably at about 8000 miles even when carbon is fired. Scraping carbon is not possible with a catalysed head, but the head can be detached and then fired, which is common practice. The benefit of the catalyser even with a Ricardo head, which is good for lack of detonation, and firing lean mixtures, is we think of special interest. Oy. M.{Mr Moon / Mr Moore} Olley MO/E COPY | ||
