ABSTRACT:
Means (1) for decreasing the rate at which a carburetor choke valve (V) closes when the engine (E) on which the carburetor is installed is shut off. First and second spaced-apart horizontal passages (P1 and P2) respectively extend through the upper and lower ends of a housing (H) in which a bi-metal choke coil (B) is mounted. A third passage (P3) extends vertically through the housing and communicates at each end with one end of the respective first and second passages. The other end of the first and second passages are connected (15,17) to a water circulating passage (WP) in the engine whereby water circulating through the engine flows through the first, second, and third passages and some of the water heat is transmitted to the housing and the bi-metal coil so the coil cools at a slower rate than that at which it otherwise cools.
