There may be a number of issues with the lawn mower. The motor may need oil or gas. The intake filter may be too dirty, clean it up then put it back in when it is dry.
The blades might not be able to spin around, maybe something is obstructing them, causing the machine to not turn over the engine / motor.
It maters what type it is but is properly the fuel line
I have a 14.5 Briggs and Stratton engine on a Ranch King riding mower that will not start. After spraying starter fluid into the head, and air cleaner it fires for a second, but will not run. It is getting gas.....coil??? or something else?
Try spraying start gas into the air cleaner.
Turn your blades off.
It depends what engine it is. If it was just a toy car yes... but if it was a mower no. what about a 50cc atv??
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.
Its ether siezed or if its electric start the silenoid might be bad.
If you have a simple push mower, the governor is a small plastic fin attached to your throttle. The fin is underneith the engine cover in the area that spins (part that you pull on a pull start mower)
if your rider mower uses petrol/gasoline then you can remove the spark plug after you have tried to start it and if there is fuel getting to the engine the plug will be wet with fuel,if however it is dry then no fuel is present.
your question needs more detail - make and HP of engine would be a good start.
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.
I am assuming that the mower doesn't start.... My first guess would be that you are not getting spark to ignite the gas in the engine. Check to see if you have spark at the spark plug.
Generally the ignition switch activates headlights on a riding mower and the start position only send current to the starter solenoid. If you turn the key and the engine cranks over than the lack of spark is going to be something else. If it is a riding mower you will have several safety switches to prevent start up under unsafe conditions.
if it is a 2-stroke engine then it only can be 1 of 3 things, the spark, the fuel or the compression.
most likely but you need to find all the specifications on your present engine by the engine model number.
If the mower has a shift knob control for "Start" "Run" and 'Stop', the kill switch will be on the end of the cable that leads to the throttle bracket. If the mower has the safety handle that shuts off the mower when it is not depressed, the kill switch will be at the end of the cable that leads from the handle to the engine. If the mower is operated with an on-off ignition switch, the kill switch wire will be spliced to the switch "off" wire some where between the throttle cable and the switch.
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.
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.
Disconnect the ignition ground to the engine and jump to the starter motor with a good 12V source.
There is no oil drain on a 650 series lawn mower. You have to turn the mower over and drain the oil from the spout you put it in the engine. Make sure the gas tank is empty
It means the engine has been fed too much gas. If you depress the gas pedal on a car or truck many times before you start it, the same thing will happen. A gas engine, whether it is a small lawn mower engine or a truck's engine works the same. It needs a certain ratio of gas and air in order to create the explosion in the piston chamber that makes the engine work.
If all oil the mower will not start. If only a little oil, the mower may start but run rough and smoke very much.
