Abstract
A choke control device for delaying closing of a choke valve regulated by a temperature responsive bimetal coil after an internal combustion engine is turned off by employing a heat sink which stores the latent heat of fusion or vaporization that is delivered to the heat sink after the choke is open and the engine is operating at normal temperatures and which releases the latent heat after the engine has been turned off and cools to heat the bimetal coil and delay closing movement of the choke valve.
