ABSTRACT:
A diaphragm carburetor for small internal combustion engines of generally standard construction but improved features for facilitating hot starting due to engine heat or environmental heat which transmits to the carburetor. An automatic or manual relief passage from the diaphragm chamber relieves pressure on fuel due to heat conductors so that a rich fuel charge will not be forced into the engine but will release to atmosphere, thus permitting a normal fuel mixture to be directed to the fuel mixing passage upon a restart of the engine.
