Honda EU6500iS Inverter Generator - Page 3 - Answered Questions & Fixed issues

The reduced atmospheric pressure at high altitude means the standard carburettor settings will not allow sufficient fuel to flow for efficient running. The dealer or manufacturer should be able to provide details of alternative settings - the jet sizes are usually increased a few points for every 5000 ft above sea level. The cooler temperatures experienced at high altitude would probably change the engine oil specification to a lighter or thinner grade.

The Honda 5.0 gc160 owners manual calls for an NGK BPR6ES for proper heat range. Should be available at any Lawnmower shop or online at ebay

I would suspect that the inverter is fine and would look towards carburetion. The inverter, in addition to supplying the correct voltage and current, monitors the current being drawn by your connected load. It controls that stepper motor on the top of the carburetor and increases the throttle to increase the engine power to support the load. (Mechanical power in = electrical power out.) Start the generator and then add a small load to the outlet, 100 watt light bulb or something. I use a space heater that I can turn on just the fan. See if it still stays running. Then increase the load (with my heater I go from fan only to the first level heat 1000w) and watch the top of the carburetor to see if the inverter increases the throttle to compensate for the increased load. By the sounds of what you are describing, it will go to full throttle and the engine will die because of a restriction on the available fuel. If that is the case, take the carb off and clean it. Or if you are not the carburetor rebuilding type, buy a new one.. they are only about $80. Not a bad fix for a $2000 generator :)

Likely a valve stuck open. Pop the head off and verify. If so, try to free it by spraying a a light oil around the valve stem and possibly rotating the valve to free it. If you damaged the head gasket removing the head, it will have to be replaced. Be careful to torque the headbolts symmetrically so as not to crack the head. There will be a troque spec but I do not know what that is.

It depends on if its over voltage or undervoltage. I would check the governor linkage and throttle settings while using a volt meter and a 100W incandescent bulb.

lack of fuel or air

i thought id answered this, if there is an eye glass check the oil level mate, its normally below one of the handles, sometimes you can screw the eye glass off and top up

really have to ask

Check the oil level, low oil will stop the engine from continued running

Yes, if you have the circuit diagram because it produce different voltage output some terminals if you got wrong your wire going to burned.

check the sump oil level test the low oil warning system

Carburetor, injectors likely gummed up. It is a common problem. Try spraying carburetor cleaner into the intake and get it to run briefly by burning the cleaner. Keep trying that until you get it to run.

There are several problems it could be other than fuel. Have you checked you have got a spark. Have you checked that the choke is working. Have you checked that the ignition circuit is live when you turn the key to on. Have you checked the air cleaner is not blocked. Have you checked that the exhaust is not blocked. When was the last time you had it serviced.

How to test your Electricity Generator AVR Brushes and Alternator on... You need to run these tests in the video and come back to us with the results. Send your test results to us here: https://www.generatorguru.com/ask-the-guru/ Then we can tell you what the problem is :)

yes alternators are not rotation sensitive

Try changing bad receptacle.

check for low oil level controller

Is the battery fully charged or has it been load tested?

SSounds like either you have a hole in the muffler or the muffler bolts loosened up.

Sticky inlet valves
