A carburetor for a two or four stroke engine having a diaphragm chamber for supplying fuel to the air intake passage of the engine, and a reservoir for primer fuel. A manually operable pump or bulb draws fuel from the diaphragm chamber into the reservoir. An outlet passage leads from the reservoir to deliver primer fuel to the engine. A normally closed manually operable valve or button is provided for opening the outlet passage. The capacity or the reservoir is varied as a function of ambient temperature by a temperature compensator.
