If you left gas in the tank all winter long, it could have built up water condensation. Always drain your tank during the winter months. I would check the fuel pump. Take the fuel pump off, leaving fuel lines attached and manually work the pump striker, check to see if it is pumping gas. You may need a new fuel pump and gas filter. If so, drain all the gas from your mower, add about half a gallon of gas and blow it through the fuel lines with an air compressor to clean any debris, then attach new fuel pump and filter. First you may want to replace your spark plug and see if that works. If your mower isn't starting, it's either not getting fire or fuel.
The engine floods and you have to wait for the lawnmower to drain before you start it up again or it might start smoking.
As long as the battery in the lawnmower is a 12 Volt battery you will be fine.
plug it in and push the on button
If the wrong oil is used in a lawnmower, do not start it. Simply drain the oil as completely as possible and fill with the proper oil.
Loss of power and hard to start.
Wait for the fuel to evaporate for a couple of minutes before trying to start it.
Get a new battery, Auto parts stores sell them.
Not on a push mower that has no electric start. On a riding mower, yes there is an ignition key.
i guess because it won/t start again
You have a bit of extra oil in the cylinder burning off for some reason
spark not ignite Check float might just need a good carb. cleaning.
It is difficult to start and emits a smelly white smoke once running.
