Abstract
An engine carburetor and a solenoid valve assembly therefor and methods of assembling the same. The carburetor has a body with a fuel and air mixing passage communicating with an air bleed passage. A cavity extends into the body for communication with the air bleed passage. A solenoid housing is received in the cavity and maintains a coil body for receipt of a valve body therein. The valve body moves between a retracted position to substantially open the air bleed passage and an extended position to substantially close the air bleed passage.

A carburetor, comprising:
- a carburetor body;
- a fuel and air mixing passage in the body;
- an air bleed passage extending through at least a portion of the body and communicating with the fuel and air mixing passage;
- a cavity extending into the carburetor body and communicating with at least a portion of the air bleed passage;
- a solenoid housing having a through bore and an outer surface with a portion received by a friction fit within the cavity in the carburetor body;
- a coil body received at least partially in the solenoid housing and having a valve passage;
- and
- a valve body received at least in part in the through bore and the valve passage for reciprocation between a first position to at least partially obstruct the air bleed passage and a second position permitting a relatively free fluid flow past the valve body in the air bleed passage.
