it's possible that u may have a worn washer underneath the governor gear it's internal this washer wears due to lack of oil change 4800 is way too high for that engine to operate 38oo max parts are inexpensive although doing the job to repair it is another it's behind the front cover of engine you need washer slider and governor gear totl cost of parts under 30.00.

from your description and what you do , the problem is in the auto control unit
it will be in the system to reduce the rpm to idle when there is no load ( auto mains on off controller switching between genset and mains supply)
by turning the auto operation off you are committing the gen set to full rpms regardless of the power requirement
you have the option of having it fixed at an gen set repair shop or leaving it off and starting the genset only when you have a mains power outage
check with an electrician to ensure that it is possible to run it that way as if the mains power unit is not correct , when you start it and you still have mains power , it will destroy the gen set

• The Auto Throttle System switch needs to be in the off position.
• If the generator has not been used for awhile than the fuel is stale and the generator may be slow in responding to the load change. Replace fuel with fresh fuel.
• Attach a second load such as a 100 watt light bulb standard bulb with a tungsten filament. Observe the light as the heater cycles. If the light goes very dim than the generator is slow responding to a load change. Generator carburetor needs to be cleaned, tune-up. Run fresh fuel under load to see if carburetor will clean itself.
• Try adding choke to see if richer mixture reduces voltage dip. Check manual for mixture adjustments.

There's a short in the 220 circuitry. Check for continuity between the two hot leads, or between the hot leads to ground

Hi,
I have a EM5000SX. My problem is my generator will not start unless I turn the fuel selector to off. Then crank it until it does start, turn the fuel back on. Run's normal . I run this generator for my cabin every weekend.

This is almost always caused by a dirty throttle valve and automatic idle speed control valve which is on the throttle body. Do the following to clean the system up.

To correct this problem Buy a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, NEVER USE CARB CLEANING SPRAY, IT DESTROYS THE ANTI-STICK TEFLON COATING, spray it into the air intake through the throttle body of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional.

96-00 HONDA CIVIC TPS SENSOR THROTTLE POSITION NEW Yes your Civic has a TPS sensor... Hope this helps

Hondas are notorius for building up carbon in the throttle body causing them to run rough and eventually stall. i would try remove the intake tube and spray carburator cleaner thru the throttle body with the car running and wiping out as much as you can reach with a rag and carb cleaner
