Several questions here...

1. Is the oil serviced to the full mark?
The oil level sensor can cause a no spark condition because it grounds the ignition.
2. Is there spark at the spark plug? You can remove the spark plug and test for spark but if the plug is internally grounded it will show spark when removed but if it is installed it can still be defective. (Spark Plugs are cheap replace it)
3. Is the handle safety cable loose even when depressed? A bad safety cable or an improper cable adjustment can also cause a lack of spark.
4. Do you note gas on the spark plug or is it very dry? If the spark plug is dry try adding a splash of gas into the cylinder via the spark plug hole and see if you get a temporary / momentary start. If you do then you have either a fuel supply or carb problem.
Make sure the fuel selector is in the ON position.
5. If you suspect a fuel problem disconnect the tank feed line to the carb and see if there is fuel flow from the tank, No fuel flow no start.... then problem in the gas tank or supply line.

I will post this as a solution but will watch for any responses and continue to assist you if needed.

Thanks for using FixYa.

    On a Honda engine the fuel selector (On / off) is co-located with the choke lever. One above the other with the fuel selector being black and the choke lever being white. If there is a problem your having I can help you. Most hard starting issues are caused by debris in the bottom of the float bowl or the fuel sump under the fuel selector valve. 95% of the time it is strictly in the fuel bowl.

    If the oil is low I have never seen an oil cut out on these engines they are sold at a discounted price over other comparable priced mowers and have a great Briggs & Stratton Engine mounted on the deck usually 6.5 h.p., while it is good to be sure the oil is full and or changed every couple of years it is not anything that will stop from starting, these engines dont incorporate a low oil cut off switch, however if you run the oil too low you can "seize" the engine and that will cause it to not turn/start.

    In all my experience the only main issues I have had with occassional stragglers is a fuel contamination problem, clean it up and should work good for a long time.

SOURCE: Yard Machines - Won't shift into gear

The problem most likely is the shaft on which the interlock slides back and forth on inside the transmission. The yardmachines have a continous spinning shaft which ends in a bevel gear. The is an interlock plate which is connected to the Forward Reverse shift lever, this plate slides back and forth and either engages the forward gear or the backward gear. This shaft is most likely galled up, preventing everything from sliding the way it needs to. This is not a difficult thing to fix if you are somewhat mechanical. Disassemble the transmission and check if everything slides

SOURCE: "how do i change the primer bulb on my yard machine lawn mower"

You should be able to remove the old one with a screw driver or needle nose pliers. The new one should have a new gasket with it.

SOURCE: GOT GASOLINE IN OIL TANK.

Empty the tank of the tainted gasoline (Maybe add the right amount of oil and use it for a trimmer, etc), fill tank with fresh gas and clean the spark plug, since it is probably fouled out. You may have to clean the carb with some carb cleaner, and clean your plug a few extra times, but it should be fine. Hope this helps. Good luck.

Remove gas cap. If mower now runs without stalling, your problem is the vent in the gas cap is blocked. Replace the cap. Common problem!

Where is the primer ball


It may not have a primer ball. If it does, it would be attached to the carberator. If it starts, but won't stay running, that could mean your carberator needs to be cleaned/serviced.

Mower starts but won't stay running


check the inside of the cap. Check the underside of the gas cap for a cardboard disk. Remove the disk, and try starting again. My mower had same problem, and I removed the disk and suddenly it ran like there was no problem at all.

You probably have in your area a number of small engine repair shops. You will have to get on the phone and start calling around for a used mower deck. They usually have many old mowers in there yards. If you decide you only want new it could be very costly. GOOD LUCK.

How old is this lawn mower, and have you replaced the spark plug recently?

Also, check to make sure the air filter is not clogged, preventing the engine from breathing.
