Homelite generator wont run smoothly
[Return to Topics]

Help! Ive got a homelite lrxe5600 generator to be used for emergency power. The problem is it wont run evenly, it surges, the motor keeps reving up and down, it does this with the aouto idle on or off. it makes the lights in the house get brighter and dimmer and it does this either when hooked up to the transfer switch or when just plugging into an outlet on the control panel. is there any way to smooth out the throtle control on this unit. thank you for any help Jeff W.

Clean, inspect and then adjust the carb.
Clean or replace the air filter.
Replace the spark plug.
Replace the inline fuel filter.

Pretty standard stuff.

You can first try adjusting the main needle (usually points straight up in the middle of the fuel bowl on bottom of carb on small engines).
Start the engine and put a load on it (hook it to the elecrical system). Then turn the main needle out slowly till the engine smoothes out.

You have to understand however, that the surging is indicative of poor fuel flow, either due to a clogged fuel filter, bad gas, or a gunked up carb.
Simply adjusting the carb may buy you some time, but you may have the thing stop when you need it most.

I suggest some routine maintenance...

First thing to do is tweak the mixture setting on the carb. Generators run at full throttle all the time, so adjusting the high speed jet may smooth it out.

If that doesn't work, and you're sure you have fresh gas and no crud in the tank or carb, the next thing is to check the governor. Not sure how that works, as it depends to a certain extent on make and model of the engine, but you should be able to get a book. Or, a small engine mechanic should be able to fix you up.

sorry i neglected to mention that the generator is brand new and the auto throttle is what is reving the engine up and down. when the load is taken off it idles down and runs steady, when load is aplied it revs up hits the correct voltage then the throttle revs the motor down to a lower voltage then revs back up then down etc. that is what is causing the surging. my question is, is there any way to get the motor to run at a steady rpm to keep the voltage steady. thanks J. W.

Brand New Out Of The Box and it has problems?
Go on now... ;-)

Sorry about the sarcasm, but the advice is still valid.

What is happening is that the motor sucks gas...gets up to 'governed RPM'...and then starts to starve for fuel because the bowl can not fill fast enough to supply the engine so it slows slightly to keep from stalling and let the flow catch up with demand. At idle it will not rev up and down because constant fuel flow is sufficient to meet the unloaded demand.

Adjust the carb main needle under full load till it smoothes out...
