Hi Jerome If your exhaust valve guide seems ROUGH as the exhaust valve travels up and down in it, use some strong solvent on it to break up the carbon and clean it. The stronger, the better. If the valve is removed, of course the job will be much easier. There are a variety of solvents out there you can use to break up and clear away carbon on the guide and on the valve stem itself. It may take a few rounds of using it, but after a time, it can be cleaned.
