How a Snow Blower Carburetor Works

Carburetors are slightly different from each other in design and operative complexity. the simplest variety that is usually a long straight air pipe-shaped carburetor right above the engine cylinder. Here fuel pipes are attached horizontally on one side.

There are different types of carburetors available for a snowblower as well. They may range in size and costs, however, their working phenomenon is pretty much the same. Let’s check it out!

  1. Through the engine air intake system, air enters the carburetor which is controlled by the choke. By turning the choke valve off less air would pass down along the pipe and ultimately engine will get abundant fuel to start up. It is not an automatic valve you can change its settings manually.
  2. Air then reaches to narrow obstructive part of the pipe called the venturi
  3. As a result of this passage of air, a vacuum is generated. Fuel is pushed in to cover this vacuum and eventually, the engine gets power from this fuel to start up.
  4. The float chamber is attached to the end of the cylinder with a float valve on its top to hold extra gas.
  5. When the gas is released into the chamber, the float falls and un-blocks the opening of the chamber. The float valve lets the fuel bowl refill if the gas in the float chamber decreases
  6. Gas is released more rapidly when the throttle valve is open and hence, the equipment goes faster.
  7. Finally, the throttle gets close and the engine is disconnected.
