What Causes a Scooter to Frequently Stall When Decelerating?
1 Answers
The reasons why a scooter frequently stalls when decelerating are as follows: 1. Clogged fuel filter screen: Insufficient fuel supply after accelerating causes the engine to stall. After stopping, gasoline flows back into the float chamber, allowing the scooter to restart. However, when accelerating again, the fuel level in the carburetor drops, and the main jet cannot draw fuel, leading to another stall. 2. Clogged carburetor main jet: This may be due to dirty gasoline or long-term inactivity of the scooter, causing fuel deterioration and forming deposits that block the main jet. 3. Engine overheating causing slight cylinder expansion: If the cylinder is expanded, it is necessary to go to a repair shop to replace the cylinder block, piston, and piston rings.
