valve setting on os fs70
I WOULD LIKE TO KNOW THE VAVLE SETTING ON A OS FS70. I JUST REPLACED A NEW HEAD ON MY FS70and am using the valves out of the old engine which is really a almost new engine.

RE: valve setting on os fs70
The proper valve setting for the FS70 is between .04mm and .10mm. Engine cold and piston at Top Dead Center. (Turn over until compression is felt the 1/4 turn more). The .04mm gauge should pass between the rocker and the valve and the .10mm gauge should not.
You can download the manual for your engine at the OS Engines web site(www.osengines.com). Available in .pdf format.
Hope this helps.
