<p>PROBLEM TO BE SOLVED: To prevent a dent on a throttle valve so as to prevent the occurrence of operational discomfort by effectively using an assembly error preventing pin in a piston valve type carburetor.SOLUTION: A guide pin 4f and an assembly error preventing pin 4g are formed of a material harder than that of a throttle valve 4b. The assembly error preventing pin 4g is disposed separately from the guide pin 4f in a reciprocating motion direction of the throttle valve 4b. The assembly error preventing pin 4g is disposed at a position where the assembly error preventing pin 4g is inserted into a slit 4b1 of the throttle valve 4b irrespective of a reciprocating motion position of the throttle valve 4b.</p> |
