How throttle and choke linkage is setup on a Briggs 2 piece?
How does a lawn mower throttle work?
When the crankshaft spins quickly, the flyweights open up, putting pressure on the governor cup and crank. This closes the throttle, limiting the air-fuel released into the engine. When the engine load increases, the crankshaft spins more slowly. This leads the flyweights to relax and the throttle to open back up.

What causes a Briggs and Stratton engine to rev up and down?
A lawnmower that hunts and surges may be experiencing something as simple as an airflow issue. If the air that the engine requires to run is blocked, especially sporadically, it can cause the engine to slow down. When the blockage moves or clears, the engine may suddenly rev up in response.
Do you open or close a choke to start an engine?
An engine needs more air as it warms up, so the choke needs to open to allow more air. With a manual choke, you will need to close and open the choke yourself when starting your engine, while an electric choke will control the air supply itself when the engine is started.
What position should choke be in?
The choke is located before the throttle, and manages the total amount of air going into the engine. 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.

What controls the choke in a carburetor?

The choke circuit consists of the butterfly or choke plate, the pull-off (also called a vacuum break), the choke spring, and the fast-idle cam and screw. Butterfly: The choke plate should fully and easily close against the air horn when the throttle is opened slightly and the spring has tension on it.
What happen if the choke is partially close?

What happens if choke stays closed?
Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. This is also bad for the environment. The choke is mainly used during winter to help with starting. The engine needs its fuel to be vaporised in order to burn it.
