Honda engines are generally extremely reliable. In my experience when they won't start it is fuel related. Not out of fuel but a problem with getting good fuel. First thing though, make sure there is enough good (fresh and clean) in the fuel tank. Next make sure that the fuel cap is not over tightened as this can limit fuel flow. I am assuming you double checked and have the proper levers in the proper position (choke to start etc). Now try it, did it start or show signs of starting?
The usual answer is to drain the float bowl on the carburetor. From the front of the mower, lean it backwards and look at the bottom of the carb. On about the bottom of the float bowl, there should be a small hex bolt, 10 mm as I recall. Carefully remove it, trying not to drop it into some hard to reach place. Set the mower back down and watch the fuel drain out. It probably isn't pretty. Probably has some water and some junk in it. Run the fuel lever back and forth a few times, leaving it in the on position till the fuel looks normal (like the fuel you put in the tank). Now tip the mower back and re-install the hex bolt. It doesn't have to be real tight, just snug.
Run the fuel lever a couple more times, put it in the choke position and try again. I'll bet it starts!
Other occasional culprits - dirty or clogged air filter, whiskered spark plug, debris blocking the fuel lever travel.

Needs cap and rotor
It depends on if you bought a pull start mower or a power mower. The pull start mower will have a handle you have to pull hard to start it. The power mower should have a button that simply turns it on. Make sure there is gas in the pull start mower.
Blocked air filter, need spark plug replacement,
There are several reasons why your mower will not start. There could be an obstruction in the blade, a petrol mower could be low on petrol or the fuse could have blown in an electric mower.
No for your lawn mower you will just need regular lawn mower oil.
The safety switch to start the motor on a Ranchking riding mower is located in the ignition. If the clutch needs to be depressed several times before the mower will start, there might be a problem with the adjustment of the clutch.
Maybe your battery is dead. But try to pull start it. At the bottom pull the handle( like a lawn mower) and hold the black button (the one next to the shift buttons. Hold it while u pull and it will start!
It is possible that an electric start lawn mower will not start because the starter is not working properly. The ignition may also be malfunctioning.
If all oil the mower will not start. If only a little oil, the mower may start but run rough and smoke very much.
Try changing your ignition coil....they're a common problem with hondas.
Does it it start sometime and not others? Does it click when you turn the ignition to start but doesnt start? Then its probably bad. Make sure your battery is fully charged first.
