Common faults of gasoline generator carburetor, how to troubleshoot?
The carburetor is one of the key components of the engine. Its working state directly affects the stability and economy of the engine. The important role of the carburetor is to evenly mix gasoline and air to form a combustible gas mixture. It is necessary to provide a combustible gas mixture with a suitable concentration to ensure that the engine can work most effectively under various operating conditions.
1. Poor start: improper idle speed adjustment, idle speed channel blocked, choke door cannot be closed.
Remedy: Adjust the idle speed according to the idle speed adjustment method; clean the idle speed hole and idle passage; check the choke valve.
2. Unstable idling: improper idling adjustment, blocked idling passage, leakage of intake connection pipe, serious throttle wear.
Remedy: Adjust the idle speed according to the idle speed adjustment method; clean the idle speed hole and idle passage; replace the throttle valve.
3. The gas mixture is too thin: the oil level in the float chamber is too low, the oil quantity is insufficient or the oil circuit is not smooth, the main injection needle is adjusted too low, and the air intake part is leaking.
Remedy: recheck and adjust the height of the oil surface of the float chamber; adjust the position of the oil needle; clean up and clear the oil path and the carburetor measuring hole; replace damaged parts.
4. Gasoline engine mixture is too thick: the oil level in the float chamber is too high, the measuring hole becomes large, the main injection needle is adjusted too high, and the air filter is blocked.
Remedy: recheck and adjust the oil level of the float chamber; adjust the position of the oil needle; clean the air filter; if necessary, change the volume hole.
5. Oil leakage: The oil level in the float chamber is too high, the gasoline is too dirty, the needle valve is stuck, and the oil drain screw is not tightened.
Remedy: recheck and adjust the oil level of the float chamber; clean the oil tank; check or replace the needle valve and float; tighten the oil drain screw.
6. Large fuel consumption: the mixture is too thick, the oil level in the float chamber is too high, the air volume hole is blocked, the idle speed is not adjusted properly, and the choke valve cannot be fully opened; the air filter is too dirty.
Remedy: clean the carburetor; check the choke valve; check and adjust the oil level of the float chamber; replace the air filter; adjust the position of the oil needle.
7. Insufficient horsepower: the main oil system oil passage is blocked, the oil level in the float chamber is too low, the mixture is lean, and the idle speed is not adjusted properly.
Remedy: clean the carburetor; check and adjust the oil level of the float chamber; adjust the position of the oil needle; adjust the idle speed according to the idle speed adjustment method.
Is it easy to operate a small gasoline generator for home? Small petrol generators for home use must be simple and practical. Each petrol generator produced by Youkai uses non-contact transistor ignition, which can achieve zero contact contamination and no mechanical wear, and greatly improves operability. Sex, security. Should consider whether the small domestic generator is easy to move? Small petrol generators for home use are generally very small. If you want to travel or have a picnic, you can also use it as a mobile power supply. What is the voltage? It is clear whether the voltage is 220v or 380V.
