What controls the Choke on Briggs and stratton 4.5?
October 29, 2008 2:57PM
There are several systems used by Briggs for choke control. Auto choke engines are equipped with a heat sensitive bi-metal coil attached to the exhaust. When cold, the coil closes the choke plate. When heated by exhaust gases, it opens the plate. Most other models have a manual lever to open and close the choke or a primer bulb system.
