The clutch spring won't do it, the spring holder is broken, I need to replace the whole clutch assembly I think?
Yes when I saw the oil the first thing I did was to drain the bar oil.
I do not understand your first line?
Piston stop....to hold the piston in place while you MANUALLY turn the clutch off in a clockwise direction...
You should have gotten a black plastic one from Stihl when you bought the MS460 in your signature...it was in a little orange bag
If you dont have one a length of starter cord down the sparkplug hole will do the same thing....
Your tryingto keep the cranksaft from turning....
DO NOT USE AIR TOOLS, and yes its CLOCKWISE....
if you need to replace both that clutch and oil pump...your looking at a couple hundred $$$..
