After much trying, mower will not start

Remove the kill wire from the coil. If it starts then it's probably a safety switch.
Also, remove the fuel solenoid and snip the end of it off.

Hello
I ordered a compression tester off of Amazon, the engine has zero comprehension.
I tried several times, nothing.

I checked the oil and it's very clean.

Could this be a valve issue?

Thanks
Dan

You either have a broken crank rod if piston isn’t moving or a stuck valve if piston does move. Like suggested above you can remove the spark plug and spin engine by hand to see if it’s moving.
