The lifter bucket, which is on top of the valve stem, and the spring in the Overhead Cam engine aides in adjusting the valve clearance.
Take a pushrod and push down on the plunger in the lifter. A hydraulic lifter is spring loaded.
It is cheaper than replacing the lifter
That is the hydraulic lifter
governor near air filter... don't adjust it too much or it will eventually blow the engine.. youtube has instructuions on how to properly adjust the spring
If it's actually the rockers arms that are "chattering" while the engine runs, you may need to adjust the lash. If there are Solid lifters in the engine, you may want to switch to hydraulic lifters and adjust the rockers to the moment of "zero lash". Adjust them in pairs per cylinder while the lifters are in the down position (both valves closed). When you reach zero lash on the rocker arm (the pushrod will suddenly stop spinning freely in your fingers) add an additional quarter turn to the rocker arm nut to set the "pre-load" of the lifter. This just means that the pushrod will be pushed down slightly in the spring loaded hydraulic lifter and when the engine runs, the oil pressure will keep pressure on the lifter and thus the rocker arms will run silently.

You can't, It is spring loaded and it adjust itself.
It is on the front ot the engine and it is spring loaded and not adjustable,.
You don't. The timing belt should have a spring loaded tensioner which pulls on the belt to adjust tension.

You could take off a rocker and try to push down on the pushrod. You'd be able to feel the spring in a hydraulic lifter, but not on a solid lifter.
Depends on the model of Onan. Some have an adjustment screw you turn in. Some adjust with a nut on a threaded shaft that pulls on a spring. Some have an electronic governor control. That you adjust with a small screw driver
