How does one start a gas-powered mower?
I'm house sitting and I've never used a gas-powered mower before (as a child chores were divided by gender and the only time I lived in a place with a lawn as an adult, I had a push power). I filled it up with gas, pushed the red button and pulled the cord but nothing happened. There's an extra handle as well: do I squeeze it or not?
There should be instructions on the machine. I'm going to give you a general rundown; it may or may not work.
1. Make sure the gas is turned on. Some mowers have a switch for this, some do not. If there is no switch, you can assume the gas is on.
2. The red button is the primer. Push it 5-10 times in succession.
3. Hold down the killswitch (the handle you're talking about) and pull the cord until the engine tries to turn over.
4. Push the primer a few more times, hold down the handle, and pull the cord until the engine actually starts. If you let go of that handle, the motor will stop. If that does happen, you do not need to prime it again (you only do that when the motor has been off long enough to cool down), just hold the handle and pull the cord until it restarts.
If the machine has a choke, make sure it is open the first time you try to start it. Once the motor starts running, slowly close it. If the motor starts to sputter as you close it, stop until the motor runs solid, then start closing it again. Repeat until it is closed and the motor is running smoothly.
