Clean off the fuel connect points. Probably just not a clean line from sitting so long since last use.

replace spring apparently it lost its tension for it to stay open you may also have a dirty carburetor if it does not run smoothly with the choke wide open have it serviced or clean it yourself if your mechanically inclined it should be a piece of cake.

For your question, i have replied many people, why generator set can start but not generate electricity?
Here is some reasons for reference:
1.After the diesel generator is stopped, the residual magnetism is often lost, because the material used for the magnetic pole of the exciter is close to the soft steel, and the residual magnetism is small. After the shutdown, when there is no current in the excitation winding, the magnetic field will disappear.
2.The magnetic pole of the diesel generator loses its magnetic properties.
3.Damage of excitation circuit components or circuit breakage, short circuit or grounding phenomena.
4.The exciter brush is not in good contact with the commutator and pressure of brush holder is insufficient.
5.Excitation winding wiring error, opposite polarity.
6.Stator winding and rotor winding of generator set open circuit.
7.Poor contact between diesel generator brush and slip ring, or insufficient brush pressure.
8.Diesel generator lead wire wiring is loose or switch contact is poor.
9.The fuse box is fused.
10.The "auto-manual-de-excitation" switch on the control panel is in the de-excitation position (automatic generator set has "auto-manual-de-excitation" switch).
11.The voltmeter is damaged.
12.Rotary rectifier module is damaged.

Most of the time it is either the Capacitor or AVR that has blown (depending on what is fitted on your generator.). Check out our videos on how to test them.

I think there is overload .kindly measure ur load of consumption. Do not run the generator set with high load it can be cause of circuit breaker Tripp off .

Honda Electrical... | Answered on Jul 27, 2019


you probably have either a bad capacitor or more likely a short stator winding due to previous overloading

Verify that the double gang circuit breaker is good on both sides. Check for loose wire on breaker or receptacle.

If it's on a Ryobi Generator then it should be a real Honda Engine. It's possible that it's a knock off or was replaced with one. If you bought it new from a reputable source then it's real, if it's used or came from an offshore source for a really low price then it's a good possibility that it's a kkoxk off. In all honesty, from my experience they do a great job with the knock off engines & they're usually reliable and last a normal life span similar to a real name brand.

Either way, that mechanical Issue Remains, I'm assuming you're refering to the valve being stuck and basically keeping the engine locked up and not allowing it to the over when attempting to start it. Sounds likely. Did you take the spark plug out and turn it over to see if it'll turn over at all to ensure it's not just totally locked up? My suggestion would be to Remove the valve cover and spark plug so that you can see the valvetrain in action when(if so) it is turning over and observe it to see if your valve theory is correct!

Thanks and good luck my friend, see the infinity below please, have a great day!
