Running a chainsaw with the brake on can be dangerous for you and anyone in your vicinity. The chainsaw will not cut, but it still creates sparks that can cause fires or startle nearby pets.

The choke position increases the richness of the air and fuel mixture the carburetor sprays into the cylinder. With the master control lever in the choke position, the flow of fuel into the engine increases and the flow of air decreases.
What is idling chainsaw?
If the chainsaw won’t stop spinning when idling, or it’s smoking when it idles, it’s getting too much fuel and running rich, so you’ll need to back it down a bit. If it’s accelerating too slowly, or sputters and jumps erratically when idling, it’s got too little fuel and needs more.

What happens if you run a chainsaw without bar oil?
