You didn't say, so I'm assuming that this is an LP Vapor fueled Home Standby generator. The bottom line to these things is that if it sounds like a fuel problem it almost always is one.

1 - Check for leaky fuel supply plumbing.

2 - Check the fuel pressure at the input side of the demand regulator inside the generator, it needs to be something like 11 inches of water all the time. My Generac/Guardian training came with a nifty manometer just for this purpose. If you can't get a manometer your LP supplier should be able to come and make this measurement for you. If you aren't comfortable with adjusting the gas pressure you should call them anyway.

3 - Change the spark plugs. This isn't all that common a problem, but it's cheap compared to changing the demand regulator.

4 - Check/replace the demand regulator inside the generator. This part controls gas flow rate rather than gas pressure so if the diaphram in there gets sticky or leaky you can have fuel problems.

My generator Jetman gg7200e idles uneven it accelerates and decelerates all the time unless i keep the choke nearly closed


That kind of surging usually happens when you are running out of gas. Is the fuel tank full and is it getting enough fuel to the carb when it needs it?

Yamaha 5200d it starts and runs 2/3 minutes and shuts down oil is full low oil lite does not light up carb is clean


This generator is equipped with an auto choke. What is likely occurring is as the engine warms up the choke is returning to the normal choke off run position leaning the mixture two lean to maintain operation of the motor.

This is occurring because the residual fuel that was left in the carburetor has evaporated and the gum residue is reducing the fuel flow through the carburetor. When the choke is applied the mixture is rich enough to support running and as the choke returns on its own to the run position the mixture leans out and the generator stalls..

Override the choke when the engine is starting to falter to confirm the problem. Continuing to attempt to run the engine possibly adding a carburetor cleaner additive to the gas will likely return the unit to normal operation.

If attempting to enrich the mixture by applying choke when the engine begins to falter does not work then a fuel flow problem to the carburetor may be the root cause. I would look for a plugged fuel filter or restricted fuel flow from the tank to the carburetor. What is happening is when the unit is at rest the carburetor is filling with gas and as it is running because of a restricted fuel flow the level lowers in the carburetor bowl resulting in a mixture to lean to run.

I have cleaned the gas tank, fuel lines and rebuilt the carb. It now runs but just at idle almost in the choke position. I have played with the throttle and it wants to die when I move it to normal ru


if it runs only in choke it sounds like its lean (choke reduces airflow and gets back to a mixture it will run on.....just). It could just be a small bit of crud in the carby jet. You cleaned the fuel system.....did you install or replace a fuel filter? sometimes cleaning the tank and lines stirs up stuff that needs to be filtered.....even though you may had cleaned and rinsed out a lot.

Honda eu3000is does not operate without choke


It sounds like your fuel mixture is too lean, closing choke is richening the mixture, by closing off air

When I start my generator it just lugs and shakes and will not get going. I have a UST 2300w generator modle GG2300. thanks jeffery


OK, you have a hard to find info on model. My first thought is that your choke is still on.
Does it have a manually activated choke? If so you know what to do, after she kicks, turn it off.
If it is one of the new Auto-choke units you may need to find the choke linkage and disengage
it that way. I have asked for a manual for your from UTS. We will see what they send, or dont!
As with all engines, if left in storage for long periods of time, use fuel stabilizer and try and start
the engine every 30 days and let it run for 10-15 minutes just to warm up and keep everything moving.

Hi there, YES manual VERY misleading, starting it all revolves around the Choke, if I remember correctly, place lever on Choke, start then move lever to on position, good luck

Will not start when cold if you ues starting fluid and get it running it will stay running until its shut off but if it sits and cools down for approx 1 hr it wont start the fuel valve was just replaced...


Sounds like the choke is not closing. Perhaps it has become detached from the manual throttle.
A simple test you can perform is to let it cool for an hour or more, remove the air filter and cover the air intake with your hand (making your hand a manual choke). If it starts right up, then the real choke is the problem.
There are two valves that you can see from the top of the carb. The one closest to the air cleaner is the choke. The other one is the throttle. Both valves operate through 90 degrees of rotation. The choke should close all of the way with the lever in the start position and be open all of the way with the lever in any other position.

Yamaha 6600de generator dies 3 seconds after starting


When you pull the bowl off of your carb is it clean? If not you have some contamination possibly inside. You might want to remove the carb and blow compressed air through all the vents a ports.

It starts fine and runs on choke but not off choke


It sounds like you are not getting enough gas. I think it's the diaphragm, When you take it off of the choke diaphragm controls the gas flow, apparently yours is just shutting down. It's very inexpensive, and very easy to replace. Good Luck :)
