Take a close look at the governor and its associated springs. There should not be any play in the governor arm, springs should be taught when engine is off.

The governor spool may also be binding, but much harder to check since it is internal to the engine.

Start the generator, and watch the governor arm. When RPMs drop, you should see the arm move in an effort to open the throttle. Conversely, when the engine races, you should see the arm move in the opposite direction to try and close the throttle. Small movements of the governor are normal with a steady load. If you don't see the governor trying to correct engine speed, you likely just identified the culprit.

Why doesn't it start?

gen sets have to be run at set rpms so that the voltage and cycles are correct for the applications
with the rpms as little as 100 rpms below requirement , the voltage will be down , causing a brown out which burns out electric motors and if the rpms are low the required cycles will also be off which affects electronic equipment
service the gen set and find out why the rpms are not at the set level

2005 Dodge Ram 1500 4.7 Engine. Starts fine, Idles fine, but when engine shifts into high gear and RPM lowers engine runs really rough under load

Have you checked for a broken valve spring. Repaired a dodge engine with the same running issue as you have described and it was a broken intake valve spring.

Honda eu3000is shuts off suddenly?

There are two likely causes.
Honda generators have an oil level sensor which kills the ignition when the oil level drops too low. Check the oil, and if it shows there is enough, temporarily disconnect the wire going to the level sensor switch--usually a black wire with a white stripe--and see if the problem goes away. Oil level switches can fail intermittently, causing engines to die after they run for a while.

Exhaust valves with an insufficient gap can also cause your problem. A cold engine will start and run but as soon as it warms up, it will die. When the engine cools down, the engine will start easily, warm up and die again. Check the valve gaps when cold and adjust to meet the specification, usually 0.003".

High voltage?

Make sure the engine RPMS are correct, and change the capacitor in the end of the alternator cover

98 eclipse 2.0 idles high at 2500 rpms an I just replaced the throttle positioning sensor

sounds like you may have a vacuum leak. any air entering engine not passing through the throttle body will cause engine to race. a whistling sound is sometimes a sign of vacuum leak but not always audible. propane is the recommended method finding leak but I find this unreliable. spraying carb cleaner around suspect areas and listening for a rpm change is more successful. just remember carb cleaner is extremely flammable and caution must be used.

Can i run my bose speakers from a powered mixer

You have not mentioned which model of Bose. But anyway simple rule of thumb is make sure your amplifier output power does not exceed the speakers rated power. Speaker power rating can be higher than the amplifier . That way you won't damage the speakers.
Just remember you cannot use a domestic speaker system for a commercial purpose because they are not designed to throw sound over a great distance and cannot generate very high sound pressure levels like professional speakers do. You may not achieve any satisfaction and in return may damage the speakers by turning up the volume very high. Its like trying to race with a domestic car in a formula 1 race !!!!!.Its a loosing battle all the way.

Powermate model 544000 generator undervoltage

There are basically 2 possibilities that can cause this.

1) Enigne RPMs are too low. but, since you already played with the throttle, this probably isn't the case. RPMs should be about 3600 though.

2) The voltage regulator / capacitor has high ESR (resistance) or is bad altogether. Replace.

Idles high drops to normal then increases again

either a vacuum hose has come loose or is worn/cracked, or you might have a leaking head gasket.
when engine is running at a normal idle,... spray some carb cleaner around hose fittings and the intake manifolds one carb at a time..if the idle goes up..there's your problem.

Marine electronics should never be powered through an ignition switch. A sudden drop in voltage will cause it to shut off. If your boat is powered by a four stroke outboard it probably is not generating enough current to meet the demands of the engine and the electronics. Four stroke outboards generally have to run at high rpms to generate enough current to charge the battery. Old or poorly maintained batteries could also contribute to your problem.
