Abstract: A carburetor is provided with a primer for aiding in starting an engine, the primer including a priming bulb for forcing air into the air space in the float bowl to cause the air pressure in the air space to be greater than atmospheric pressure and to cause liquid fuel to be forced through the fuel nozzle and into said fuel-air mixture passage of the carburetor. The priming bulb includes a flexible wall having a groove and a vent opening is located in the base of the groove and is positioned so as to close as the priming bulb is compressed and as air is forced into the air space of the float bowl. The carburetor also includes a narrow passage permitting the venting of a portion of the air forced into the air space of the fuel bowl by the priming bulb to thereby control the amount of liquid fuel injected into the carburetor venturi.

Abstract: Disclosed herein is a combined clutch and brake comprising a drive assembly including a driving member rotatable about an axis and a driving disk fixedly extending on the driving member for common rotation therewith and against axial movement therebetween, a driven assembly mounted on the drive assembly for relative rotation therebetween and against axial movement of the driven assembly, a ring member located in encircling relation to the driving member between the disk and the driven assembly and including an upper surface having an annular friction pad including a radially inner portion in facing relation to the disk and a radially outer portion, a spring biasing the ring axially towards the disk for driving engagement by the disk with the inner portion of the friction pad, a brake member fixed against rotary movement and movable axially between a retracted position and a braking position engaged with the outer portion of the friction pad so as to disengage the ring from the disk against the action of the s
