These engines have a low oil sensor and if the oil is low, the engine will not have fire. So check the oil level first and make sure it is to the full mark.
Check the spark plug that it still has proper gap .028-.031 in and the proper spark plug BPR6ES (NGK) or W20EPR-U (ND). While you have the spark plug out let's see that it is firing, reattach the plug wire to the spark plug and make sure the spark plug is in contact of a bare metal surface for a ground, the crank the engine over watching for spark in the gap of the spark plug. It would be best to check this in a low light area. Keep in mind that checking for spark this way and there is spark but when the spark plug is installed and there is compression the spark may not jump the gap as it should. If no spark with the plug out check the spark plug wire for cuts or tears and it none seen get a new spark plug. If there is spark with the spark plug out reinstall the spark plug. If the engine hasn't been started for some time drain the gas out of the fuel tank and carburetor. There could be water in the fuel also but to check if there is fire get a can of starting fluid. Drain the carburetor anyway at this point because if there is water in the fuel the next step may not fire the engine because of the water. Take the air filter out and give the opening of the carburetor a short spray of starting fluid. Try to start the engine, if it doesn't start or fire with the starting fluid there is something wrong in the ignition system. The Digital CDI Ignition Coil could be bad but before buying a new one you need to check the shear key of the flywheel to the crankshaft to make sure it is in good shape. You will need to remove the flywheel for this. If the key is in very good shape, then it is the coil.
If the engine fires on the starting fluid then you have water in the fuel or the fuel is not getting into the engine as it should from the carburetor. The carburetor needs to be cleaned.
try pulling the plug, stick a screwdriver in the end of the spark plug wire and hold it to the metal of the bike try starting it if it has fire you wil get a spark. if no spark try checking the points they may have burned out ... good luck
if fuel is getting to injectors, are the injectors plugged ! if you are getting fuel to engine plus a good spark it should start. check the plugs for fouling out. maybe there not firing right. if a plug or plugs are not firing. then they will be wet on the tips of the plug. crank engine a few times, then pull the plugs to see if they are firing.if not firing, check for bad plug wires. theres so many things that can cause this. its hard to say without being there!
First you could make sure you have spark. Take the plug out and then plug it into the black wire. Set the end of the spark plug near the frame of the lawn mower. Pull the cord one time to see if there is an arc from the plug to the mower. If you have spark, I would put the plug back in. Before putting the plug back in I would spray a little bit of starting fluid. See if it will fire up with the starting fluid in there. If you have a true good spark, it should fire up. This may be enough to get some gas going in there as long as you have the lines hooked up correctly.
