There are a few possible reasons why your Husqvarna YTH21K46 won't start even if you have checked the battery, fuel, and spark plug. Here are some things you can check:
Clogged fuel filter: If the fuel filter is clogged, it can prevent the fuel from reaching the engine, causing the mower to not start. You can check the fuel filter for any signs of clogging, such as dirt or debris. If the fuel filter is clogged, you will need to replace it.
Bad fuel: If the fuel in the tank is old or stale, it can cause problems with starting the mower. Try draining the fuel from the tank and refilling it with fresh fuel.
Air leak: If there is an air leak in the fuel system, it can prevent the fuel from reaching the engine, causing the mower to not start. You can check for air leaks by spraying carb cleaner around the fuel lines and connections. If you hear a hissing sound, there is an air leak. You will need to tighten the connections or replace the fuel lines.
Bad ignition coil: If the ignition coil is bad, it will not send a spark to the spark plug, causing the mower to not start. You can test the ignition coil with a multimeter. If the ignition coil is bad, you will need to replace it.
Bad starter: If the starter is bad, it will not turn the engine over, causing the mower to not start. You can test the starter with a multimeter. If the starter is bad, you will need to replace it.
If you have checked all of these things and your mower still won't start, you may need to contact a qualified lawn mower repair technician for assistance.
