Carburetor including a manual fuel control device

A carburetor receiving air filtered by an air cleaner to generate an air-fuel mixture and supplying the air-fuel mixture to an engine main body, comprising:

• an air-fuel mixture generation passage for generating the air-fuel mixture;
• a fuel discharge part supplying fuel to the air-fuel mixture generation passage;
• a fuel supply passage supplying fuel from a fuel source to the fuel discharge part;
• and
• a fuel control device including a manually operated needle valve body, wherein by operating the needle valve body, an amount of fuel passing through the fuel supply passage is adjusted, wherein
• the needle valve body includes
• a needle hollow part extending in an axial direction and opened forward in a tip region of the needle valve body, and
• a slit formed in the tip region of the needle valve body, extending in the axial direction from a tip surface of the needle valve body, and communicating with the needle hollow part, wherein
• a body of the carburetor includes
• a body hole formed in the carburetor body and receiving the needle valve body in a longitudinally displaceable manner along an axis, and
• a step-part circumferential edge formed in the body hole and constituting a fixed valve seat forming an orifice with the slit, wherein
• the orifice is adjusted in size by operating the needle valve body, wherein
• by adjusting the size of the orifice, an amount of the fuel supplied from the fuel source through the orifice and then through the needle hollow part to the fuel discharge part can be adjusted.
