17.5HP Briggs and Stratton Valve adjustment, what are symptoms of over tightening

I have no argument with anyone. I doubt if that outfit you mention has any idea about the positioning of B&S engine piston/cam to obtain proper clearance. B&S based their clearance on the point 1/4"down past TDC.

I'm quite certain that they have a really good idea how to "position" any engine piston/cam to obtain proper clearance.
