Valve Clearance
Break-in and normal wear tend to open up the valve clearance, and may lead to a loss of
power and performance.
The valve clearance for all 4-MIX® engines is 0.1 mm. or four thousandths of an inch
when the engine is cold.
The instruction manual suggests checking the valve clearance around 135 hours of
operation.
A cylinder pressure leak down test will allow you to quickly determine the condition
of the valves and piston rings without disassembling the engine.
A special feeler gauge is required to check the minimum valve clearance. STIHL Part
# 4180 893 6400.

Well I set them at 4 thousandths now what how sure are you on the 10?
I have no idea on the specification. I am just trying to make sure the guy who is doing the adjustment with the feeler-gage is not setting is to one thousands of an inch. (0.0010)
Ok
