How do you hook up a throttle cable on a Briggs and Stratton engine?
How does the throttle work on a Briggs and Stratton?
When the crankshaft spins quickly, the flyweights open up, putting pressure on the governor cup and crank. This closes the throttle, limiting the air-fuel released into the engine. When the engine load increases, the crankshaft spins more slowly. This leads the flyweights to relax and the throttle to open back up.

What controls the throttle position?
A throttle position sensor is used to measure how open the throttle valve is and therefore controls the amount of air which can flow into the engines intake manifold.
What causes the throttle not to work?
Build ups of dirt and grime can cause airflow and pressure problems in the throttle body or the issue could be an incorrectly adjusted throttle stop, which is also part of the air intake system. Uneven airflow will cause pressure problems in the system, which again could lead to poor performance and acceleration.
How is a throttle body supposed to work?
A throttle body is a butterfly valve located between the air intake filter and the intake manifold. It regulates how much air can go into the engine, based on driver input through the gas pedal. As more air flows into the engine, it injects more fuel, thus allowing for more power.
How do throttle controls work?
It works by reading the amount of air entering the engine and then increasing or decreasing it, depending on how much the gas pedal is pushed down. When a driver steps on the accelerator pedal, it sends a signal to an electronic throttle controller who determines how much air is pushed into the engine.
What are the symptoms of a faulty throttle position?
- An unexplainable bucking and jerking in the vehicle.
- Sudden idle surges.
- Sudden engine stalling without any apparent reason.
- Hesitation while accelerating.
- Sudden surges in speed while driving on the highway.
- Intermittently flashing of check engine light for no apparent reason.
How do you adjust the throttle on a Briggs and Stratton engine?
- Remove the screws that hold the air cleaner in place with a Phillips-head screwdriver.
- Inspect the engine to locate the choke lever, also known as the choke arm.
- Adjust the throttle lever to the “Fast” or “High” setting, advises Garden Tool Expert.
Can you adjust throttle by wire?
Single throttle cable adjustment is straightforward. Any dust covers protecting the cable adjuster should be removed first. Next, the locknut should be loosened. The cable adjuster can then be adjusted in or out so that the throttle grip has the correct amount of free play, which is usually 2-3mm.
How can I make my throttle more responsive?
- Step 1: Install a Cold Air Intake. One of the best ways to improve throttle response is to install a cold air intake.
- Step 2: Upgrade the Exhaust System.
- Step 3: Install a Throttle Body Spacer.
- Step 4: Replace Spark Plugs and Wires.
- Step 5: Change Air Filters.
How do I adjust my throttle RPM?
Disconnect the idle air adjustment valve by locating and disengaging the electronic connector that holds it to the throttle body. Turn the idle screw to adjust the idle—turn the screw to the left to increase the RPM or to the right to lower it.
How do you calibrate a throttle position?
Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Throttle Valve Closed Position Learning.
How do you adjust engine idle speed and mixture?
Set idle speed adjusting screw, clockwise to increase rpm, counter-clockwise to decrease rpm. Idle rpm range should be 950 to 1050 rpms. Adjust idle mixture by turning idle mixture screw slowly clockwise until the engine runs poorly.
How do I reset my throttle position?
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Where is the throttle position sensor located?
A throttle position sensor (TPS) is a sensor used to monitor the air intake of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle.
Do you have to calibrate a throttle position sensor?
Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. First, be sure you have correctly wired, and assigned the throttle sensor signal input to “TPS Raw” in the Analog Settings.
What happens if throttle body is not calibrated?
If your throttle body is faulty, it will likely cause acceleration issues. This means that when you are pressing the acceleration pedal, you won’t feel like the car is reacting correctly, as it might not be able to reach the desired speed.
Can you bypass throttle position sensor?
Can you drive without a throttle position sensor? You can, but the engine will run poorly and not only will you waste fuel and create huge emissions, you’ll cause major carbon buildup in the engine and exhaust. That will cost you in maintenance down the road, if not right away.
