My EF2400iS surges under low loads. Seems to smooth out with larger load. Any suggestions? Throttle motor or control box?

Idle speed screw may need adjusting slightly to increase idle speed. Also Main jet and Idle mixture Screws may also be out of adjustment

Yamaha EF2800i. Voltage drop under load. Runs very smooth with no load.

Sounds like a governor issue. Check linkage to governor.

Engine not running smooth until blade is activated

ill bet this is an older briggs engine ? as they seem to need a little tlc on there governor speed control spring for it's feedback to the throttle , this makes the engine surge a bit (hunting) till a load is placed on it then it runs smooth , now if it doesn't smooth out under load id suspect a carb fuel flow problem

Briggs and Stratton Vanguard 26hp. The idle fluctuates, hunts and surges. When under load such as moving or PTO running then it quits surging and runs fine.

Hi Jahn:
Sounds like it could be a spring on the carb / governor linkage.
I'd suggest you have a relly good look around the carb, wiggle the linkages, and look for one that seems loose. If you find a dangling spring odds are you'll be on the problem.

How to fix surging on yamaha 2400 generator

If may be a partly blocked main jet ( Check by slowly closing the choke), if it the hunting clears out as you slowly close it it prob blocked main or pilot jet...
If the unit hunts (flutter)at 1/4 through 3/4 load, the governor damper spring on the throttle shaft under the stepper motor needs one more turn.. only after you've checker the carby..Only one turn or you will damage the stepper a few of these....

Rpm surge with intermediate power load

The problem is the governor and is easily fixed. Do the following: Remove back and side panels to expose fuel tank. Insert screwdriver into fuel on/off switch on front panel and remove. Now remove top panel. To do this unscrew fuel cap, pull out fuel spill surround rubber and remove top panel, just pull gently. Now with fuel tank exposed, remove retaining bolts. Gently lift tank and rest on frame. No need to disconnect fuel line.On top of carby is the governor, protected in a black plastic shield. Unscrew the retaining screws that hold it to the carby. Remove electrical connection and then remove governor from carby. Now remove cover by pressing on the three retaining plastic clips and prize upwards. Now the solenoid is exposed. Remove solenoid from its base by unscrewing the two retaining screws. Now that the solenoid is fully exposed use an spray on electrical cleaner that can be used on circuit boards. Spray the base of the solenoid in particular the spindle. Whilst spraying the spindle rotate it a few times until it moves freely. Then replace everthing in reverse order. Where the spindle exits the solenoid dust particles collect and increase the friction between the two surfaces. If you do not want to proceed as outlined tell your dealer it is the solenoid and have it fixed under warranty.
