What Causes the Throttle to Be Hard to Press?

[GemmaDella]

There are several reasons why the throttle may be hard to press: 1. Severe carbon buildup in the engine's throttle body. 2. The throttle cable is broken. 3. The vehicle's throttle pedal is obstructed by floor mats or other objects. Before driving, it is essential to inspect the tires, brake pedal, throttle pedal, and clutch pedal to avoid malfunctions during operation. The reasons why a scooter frequently slows down and stalls are as follows: 1. Clogged fuel filter screen: Insufficient fuel supply when accelerating leads to stalling. After stopping, gasoline flows back into the float chamber, allowing the engine to restart. However, when accelerating again, the fuel level in the carburetor drops, and the main jet cannot draw fuel, causing another stall. 2. Clogged main jet in the carburetor: This may be due to dirty gasoline or fuel degradation from prolonged inactivity, forming deposits that block the main jet. 3. Engine overheating causing slight cylinder expansion: If the cylinder is expanded, it is necessary to visit a repair shop to replace the cylinder block, piston, and piston rings.
