Took of the rocker cover, and just wanted to verify if the rocker assembly in my 2002650 is the older or the newer type? How can i be sure?
How about the cam sprocket, i tried to scratch it with a screw driver, and i couldn't so i suppose it is steel and thus the newer better type sprocket, anyone can verify this?
Another thing is, when I look inside the head at the exhaust valves, they are black from exhaust fume deposits, are they supposed to be shiny and clean just like the inlet valves? Or is it normal that they blacken due to the exhaust fumes passing?
