Also, a couple coats of Pam cooking spray is very effective at preventing carbon buildup on powervalves and exhaust ports. It works better if the parts are warm. I have an old oven(also picked up stupid cheap at the Salv Army) to evenly heat parts.
Same oven gets all kinds of use whenever mild heat needs to be evenly applied to anything(crank bearing installation for one).
