Abstract
A floatless carburetor with a fuel reservoir in communication with the carburetor throttle bore includes an integral primer system which is operable to introduce fuel directly into both the carburetor throttle bore and the fuel reservoir. A plurality of check valves control flow of fuel from the fuel tank into the primer system and into the throttle bore and fuel reservoir. The carburetor and primer system are adapted to be operated in conjunction with an impulse-type fuel pump, wherein the primer system is operable to manually pump fuel into the reservoir when the fuel pump is not functioning.
