Re: Carbon Build-up causing leaky valve seats on local evos?

The carbon on my pistons came right off with the use of brake cleaner and my fingers. Worked the brake cleaner in with my fingers and then scraped it off with my fingernails. I have no reason to believe that this stuff wouldn't just fall off when the time was right and get stuck on a valve seat. In a couple of the valve recesses on the pistons they were filled in pretty well with carbon, and in that picture you can actually see that the valve hit that carbon.
