Want this question answered?
Your Briggs and Stratton 5.5hp only runs with the choke on because it needs a tune up.
My engine is idling too high. How do I adjust the idle speed?
There is an arm that must go to the choke and I'm not sure where. I think the plastice piece might be broken.
You can adjust the valves on your 17 horsepower Briggs and Stratton engine by turning the adjustment screws. The adjustments screws will determine how much fuel goes into the piston chamber.
Is the rumor true? Is Briggs Stratton going out of Business?? We were told not to by lawn mowers with the Briggs stratton motors.

Try watching the video in the link below.
check that your main jet is not clogged. The reason it seems to run better while choked is simple. there is a bypass tube that siphons extra fuel when the choke plate is closed
At a Briggs and stratton dealer.
Briggs and Stratton recommends SEA30 oil.

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.
