What does better throttle response mean?
Throttle response or vehicle responsiveness is a measure of how quickly a vehicle’s prime mover, such as an internal combustion engine, can increase its power output in response to a driver’s request for acceleration.
What causes a car to stall when the throttle increases?
The increase in fuel translates into an increase in engine speed. If the throttle is stalling, a problem is occurring in the fuel delivery system and an insufficient amount of fuel is reaching the carburetor to power the engine. This problem often occurs in conjunction with the use of bad, old or poorly mixed gas.
What happens when you increase the throttle on a backpack blower?
Never attempt to adjust the high-speed carburetor screw without professional assistance. When the trigger is pressed and the throttle is increased on a backpack blower, a metal wire pulls open a vent on the carburetor, allowing more fuel into the passages. The increase in fuel translates into an increase in engine speed.
What causes a weed eater to die when throttled?
The most common causes of a weed eater dying when throttled are fuel issues, insufficient air intake, or problems with the exhaust. You should follow the path that the fuel travels to identify the issue.
When does the motor slow down at full throttle?
I will be cruising along at full throttle, then, without warning, and very abruptly, the motor slows down almost to a stop. After about a second it goes back to full throttle. It is very intermittent; sometimes it won’t happen for weeks, other times it happens 3 times in an hour.
What causes the throttle to be low at idle?
It can cause the RPM to be so low at idle so that the engine will die. This is often caused when there comes a lot of soot and dirt on the throttle body flap, which will cause less air entering the engine and therefore cause a low idle RPM.
Can a bad throttle body cause an engine to die?
A not calibrated throttle body can also cause this. You can calibrate the throttle body with most diagnostic scanners. The throttle body can affect the RPM the other way also. It can cause the RPM to be so low at idle so that the engine will die.
What kind of motor bogs down at full throttle?
I have a 1984 Yamaha 50hp, 3 cyl, oil injected, outboard motor, low hours, and is in fairly new condition. At full throttle, it bogs down. I’ve changed the gas lines, tank, and fittings.
