Abstract:
A cap assembly for limiting adjustment of fuel flow in a carburetor comprising:a cylindrical first cap having a first peripheral face, a first tab and a second tab, the first and second tabs each project radially outward from the peripheral face, the first tab being axially and circumferentially offset from the second tab; a low speed valve having a rotatable shank and a head, the head projecting from the carburetor, the first cap engaged telescopically to the head; a cylindrical second cap disposed parallel to the first cap, the second cap having a peripheral face, the first tab of the first cap being in contact with the peripheral face of the second cap when the low speed valve is in a maximum fuel amount position, the second tab of the first cap being in contact with the peripheral face of the second cap when the low speed valve is in a minimum fuel amount position; a housing having a continuous wall extending from the carburetor and encircling the valve and the first and second caps; and a lid carried by the housing, disposed over the first and second caps and having an inner edge defining an opening having a profile matching the cross-sectional profile of the first and second caps so that each of the caps can be inserted through the opening into the housing; and the caps and the lid are configured and dimensioned so that when the caps are fully received in the housing, the tabs are axially inboard of the lid and will pass under the lid when the low speed valve is rotated to adjust fuel flow.
