Don’t we miss a spoken comment ? Now I know it is a mechanical system with centrifugal force displacing balls that force a disc forward that takes along a pin in the camshaft. What exactly happens with the camshaft ? Is there some sort of Bendix built it ? Do both cams move ? Forward or backwards ? How many degrees ? Am I right thinking they move a little forward so everything stays a little more on the safe side at higher revs ?
