Tb22 engine starts and the cutting line rotates but when i try to rev it to have more speed for cutting, the engine cuts out
For model number TB22EC
Hello Vibhor, thank you for asking! First of all, try adjusting the two adjustment screws near the speed control by rotating them counterclockwise. Sometimes due to vibration the engine losses proper adjustment and requires manual readjustment. If this does not help then you need to clean the air filters and the carburetor. Next is to check the throttle trigger (part number: FIX11839169), the red part that controls the speed, and make sure it has not deteriorated. If it has then you need to replace it. If the issue persists then we would recommend replacing the carburetor (part number: FIX9119300). I hope this will help. Please feel free to contact us if you need any assistance, our customer service is here to help seven days a week.
Removed the two screws holding the fuel tank to the main unit. Removed the two fuel lines and any stuck on rubber. Installed and installed two screws to mount the new tank. Slid fuel lines on their respective connectors. Done.
emptied fuel from tank. pulled off the 2 fuel lines from the carburetor.opened the air cleaner door. removed the 2 torque screws that hold on the carburetor. removed the carburetor and air cleaner gasket. installed new carburetor and gasket and put back and tightened the 2 torque screws. closed air cleaner door and pushed the fuel lines onto the new carburetor.put some fuel in the tank. started the trimmer. runs great.
