RZT-L42 engine turns but doesn't start

I replaced my air filter and spark plug. I have enough non ethanol fuel. The fuel filter looks clean. I had the battery checked by two separate automotive stores. I had it connected to a charger. When I put the key in, it goes ruh ruh, but doesn't start, but it acts like it is trying. Does anyone have a suggestion?

Assuming you reattached the plug wire and have gas in the tank, try jumping to an automobile battery. If it starts, check the mower battery, its connections and measure battery voltage (>12 vdc). If it doesn't start, have the starter and solenoid tested.

A lot of times, when that shows up here, the valve lash needs adjusting It's usually on an OHV engine with a compression release. If the valve lash is off too much the release doesn't do its job.

You're saying the engine cranks normally, it just doesn't start, am I correct? Or is the engine turning over but very slowly and labored?
