When you say the engine will turn over only when in choke, I assume you mean it runs while chokedand then dies when you let off the choke. Check the fuel filter,the air filter,makecarburetor adjustments if necessary and ultimately, checkthe throttle linkage.
Your Briggs and Stratton 5.5hp only runs with the choke on because it needs a tune up.
The choke on a Briggs and Stratton 6.0 Gold engine helps enrich the fuel-air mixture during startup, making it easier for the engine to start, especially in cold conditions. When the choke is engaged, it restricts airflow into the carburetor, increasing fuel flow and creating a richer mixture. Once the engine starts and warms up, the choke can be gradually disengaged to allow normal airflow and fuel mixture for optimal operation. Proper use of the choke is essential for reliable starting and performance.
To hook up control cables to a Briggs & Stratton model 31C707 engine, first, identify the throttle and choke control levers on the engine. Attach the throttle cable by connecting it to the throttle lever, ensuring it moves freely when the control is engaged. For the choke cable, connect it to the choke lever in a similar manner, making sure it can fully open and close the choke. Finally, secure both cables to prevent any interference with the engine operation.
To remove the choke knob on a Briggs and Stratton engine, first, ensure the engine is off and cool. Locate the choke knob, which is typically attached to a lever or rod. Depending on the model, you may need to unscrew a retaining nut or simply pull the knob off if it's designed to slide off. Be cautious not to damage any connected components during the removal process.
There is an arm that must go to the choke and I'm not sure where. I think the plastice piece might be broken.
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.
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
Clean the carburetor with special attention to the high speed jet and fuel passage.
It is a carburetor where the engine coolant is routed through the choke system of the carburetor. When the coolant is cold the choke will close. As the engine coolant heats up it opens the choke.
depends on the engine Briggs or tech, does it have a primer bulb. but safe bet right next to the carb.
The kill-switdh wire is disconnected. loose. or broken. The kill-switch wire starts from the OFF position of the ignition switch and meets another wire that leads to GOUND to stop the engine.
The choke has to be half closed to run for two main reasons: 1. The carburetor linkage is out of adjustment. 2. Fuel flow is somehow restricted from flowing freely. This can range all the way from debris clogging the outlet of the gas tank to clogged passages in the carburetor. Could be a pinched hose or a clogges fuel shutoff valve, too.
