Do you start with choke open or closed?
The choke is only used when starting a cold engine. When doing a cold start, the choke should be closed to limit the amount of air going in. Once the car has warmed up, if the choke does not open fully, the restriction in air may result in reduced power.
What happens if you run a four wheeler with the choke on?
If a motorcycle or ATV only runs with the choke on, it’s because the richer “choke on” mixture is actually closer to the engine’s normal operating fuel mixture than the leaner “choke off” mixture. So when the choke is turned off, the engine gets too little fuel and too much air for it to run and it stalls.
How do you start a ATV choke?
The lever type choke should be in the down position during normal operation. To use the choke to start a cold engine, lift up on the lever to turn the choke on. Once the engine has warmed up, return the lever to the down position.
What is choke position?
The choke position is the fourth setting on the master control lever. This setting is used to start the saw when its motor is cold. Stihl chainsaws denote the choke position using a nearly horizontal squiggle between two vertical lines at the lowest position on the master control lever.
How does a choke work on an ATV?
By creating a richer fuel to air ratio, the engine has more gas to stay running. Once the engine is warmed up though, it won’t need the extra fuel. You shouldn’t ride or rev the ATV while the choke is on. Wait for the engine to warm up, turn the choke off, and then you can ride.
Why does an engine only run on choke?
An internal combustion engine needs a precise mixture of fuel and air to run properly. When the engine is cold, it needs slightly more fuel in the fuel/air mixture for it to start, which is what the choke does. The choke increases the amount of fuel in the mixture, creating a richer mixture.
Is it OK to open the choke on a bike?
If the bike is cold than yes! Close the choke fully before trying to start it, and do not touch the throttle. Once the bike starts and warms for a minute you can open the choke and drive away. This is a good practise as all bikes need to sit for that first minute of operation to allow for lubricating oil to work its way through the engine.
How do you open choke on cold engine?
To open the choke to start a cold engine, pull up on the switch so it is sticking straight out, 90 degrees from its starting position. Once the engine is warmed up, return the switch to its original position. Here I will answer some of the most common choke related questions I get.
Where is the choke button on an ATV?
Some ATV’s have a choke lever located on the carburetor and is on when the lever is up. Some choke levers are actuated by a thumb tab on the left side handle by pushing it to pull a cable. Either way, the choke should be open to start a cold engine.
When to use the choke on your new bike?
The “choke” is off when the choke lever is down or when the choke lever is facing you if your choke is a handle bar mount. Choke off means that the choke plate is not covering the carb throat. Tim…Ok so its a warm day and this is the first time starting my brand new bike. I gave the bike full choke and I tried and tried but it will not start.

Where is the Kill Switch on an ATV?
