RE: [DML] Re: carbon buildup

David, If I'm not mistaken resilone is a good top end cleaner and it's also
good for cleaning out the oil paths. Add to the gas in small amounts as it
will cause the engine to smoke as it burns. Top end cleaner was a blend of
oils for cleaning off the intake valves as the fuel was going thru them.
Then what wasn't burned would clean the exhaust valves. Grinding action.
