Need to know the engine model and type.
I need the valve settings for a 17 hr. Briggs mod. 311777 type 0131-e1 code 980521zd THANKS DENNIS
I assume valve clearance and it is 0.004".
.004 intake.....006 exhaust
flywheel key could be sheared OR check valve settings as likely the cam followers are on the wrong valve.
It's a valve that's over your head
The intake valve is always the larger of the two.
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.
Under the valve cover, of an overhead valve engine. They push the rockers on the opposite side of the valve stems. Overhead Cam engines do not have push rods.
what is the torque specs and valve lash on a 24 hp Briggs
the intake valve is bigger
Fewer moving valve train parts such as the push rods.
Single Overhead Valve Engine
