Is it an OHV engine? If so they would be loctaed above the piston head on your mower.
Yes They Do
You adjust the tappet. That's the thingy that pushes the valve down.
Want to watch the rather "neat" YouTube video? Take the link at the bottom!
I dont know what it is set on
Watch this video on YouTube. It will tell you how step by step. http://www.youtube.com/watch?v=NjzX-PUjKmo
Mainly, the difference is that in an overhead cam engine, the camshaft is mounted on the head of the engine, and the valves are still overhead, in an overhead valve engine (sometimes called a "pushrod motor"), the camshaft is in the crankcase.
This video will show you how: http://www.youtube.com/watch?v=NjzX-PUjKmo
A 4-cycle engine that has the intake and exhaust valves located in the cylinder head.
Try watching the video in the link below.
You can adjust the valves on your 17 horsepower Briggs and Stratton engine by turning the adjustment screws. The adjustments screws will determine how much fuel goes into the piston chamber.
Overhead valves open vertically from the head into the combustion chamber. Overhead valve engines use a system of lifters, push rods, and rocker arms to operate the valves. The cam on an overhead valve system is adjacent to the crankshaft, and the lifters, push rods and rockers work together to operate the valves. Overhead cam engines position the camshaft directly above the valves. In that position, there is much less weight of the valve operation mechanism, resulting in a potentially higher engine operating speed.
