What is the reason for the functional failure of the pneumatic sport throttle cylinder 1?

[Curtis]

The reason for the functional failure of the pneumatic sport throttle cylinder 1 is due to excessive fuel injection. It is recommended that users replace the spark plugs and clean carbon deposits. The specific measures are as follows: 1. Check whether the oil level in the float chamber is too high: If the oil level is normal, check whether the choke valve is open and whether the air filter is dirty or blocked. If the oil level is too high, adjust it. If the oil level cannot be adjusted to the normal height, check whether the needle valve is sealed and whether the float is broken. 2. Check the carburetor: If all the above checks are normal and the mixture is still too rich, check whether the main metering hole of the carburetor is too large, whether the economizer is malfunctioning, and whether the air metering hole is blocked. For carburetors with a main metering hole dosing needle, check whether the dosing needle is unscrewed.
