Hey Everyone!
I thought I'd show a quick video of what ACTUALLY happens to your small engine carburetor when you access and move the choke lever.
This applies to all small engines with a choke, but in this case, it is on a 7hp 2 stroke Toro R-Tek engine.
The choke lever is attached to a butterfly valve inside the carburetor, which closes (almost) fully when the lever is actuated completely. This prevents the full amount of air into the cylinder and instead allows a richer fuel mixture (as the same amount of fuel enters the cylinder). This is done because a cold engine needs more fuel to start, especially in a snowblower when its very cold! Once the engine warms up, that's when its time to reduce the choke and eventually back it off completely to run at maximum effort!
Thanks for watching!
