On older, carbureted engines, cold stalling (and hard starting) is most
often due to an automatic choke that is sticking, misadjusted or
broken. Cleaning the choke mechanism with aerosol carburetor cleaner
may free up the choke allowing it to work properly again. If the choke
housing as an electrical heating element, the element may not be
receiving voltage when the key is on, or the element may have burned
out (check resistance with an ohmmeter).
Other causes of stalling with a carburetor include an idle speed
adjustment screw that is set too low (turn screw to increase idle speed
rpm). The engine may stall if the idle fuel mixture screw(s) are not
adjusted correctly or the idle mixture port(s) are dirty or clogged
with fuel varnish deposits (clean the carburetor and readjust the idle
mixture screws for smoothest idle). Stalling can also occur is there
are vacuum leaks in the carburetor, under the carburetor (bad base
gasket), or any vacuum hose connections to the carburetor or intake
manifold
