Well we do not get that brand down here but the spring around the governor / throttle rod looks way too heavy for a damper spring
On most newer generators the only control the user has is the low idle speed.
The governor does the rest.
The low idle is set by the screw while measuring the output voltage and get cranked up till it measures then minimum line voltage.
Down here where we have 240V & 415 V they get set to 220 V
Then you hook up a heavy load & measure the voltage again as the generator accelerates.
If the voltage drops then you crank up the low idle a bit more.
If the carby throttle is sitting against the throttle stop & the engine is racing then some one has screwed it up.
Not uncommon to have one come in where the dopey owner has wound it up to 4000 rpm which burns up the output voltage regulator.
Also double check that the governor arm is set correctly on the governor shaft.
A racing engine will result if it is set up backwards.
You may have something with that. This is, apparently a Honda knock off. Surely you have those.
I'm gonna move that spring first thing. And remove the added spring on the back of the gov arm, and see what happens.
UPDATE:
When I plugged in my GCFI tester into the socket, it shows an open ground. Not sure if that's normal. I wouldn't think it is.
The gov should pull the throttle *closed*, and the tension on the spring from the throttle control pulls it open . . . IE throttle should be at full with the engine shutdown and throttle at full. As the engine comes up to speed, the gov will *lower* the throttle to maintain speed. Gov link is typically hard from gov arp to throttle plate, and throttle control to throttle (or gov arm) is the spring. Anything else will likely end poorly . . .
The gov works by flying weights that pull more the faster it runs. If the gov isn't pulling as the engine speeds up, either you are doing the arm adjustment errantly, or it may be broken inside the engine. Remember: gov should pull the throttle *closed* as speed increases (well, unless this is some odd, ***-backwards engine . . . a).
Any idea (may have missed it0 who made the engine, or is Champion just selling it as their own brand?
The governor GOVERNS.
Ie it is what slows the engine down according to the engine speed.
When stationary the governor ALLOWS the throttle to open fully
When the engine is running it either applies the brakes to slow it or ALLOWS it go faster.
So the governor works AGAINST the throttle spring to regulate the speed that is why the connection to the throttle control is via a spring and not a solid wire.
If yo remove the throttle spring as was the case in your first photo & start the engine you can get a feel for the governor by working the governor arm with you finger.
What you should feel is the governor pushing back against you finger the faster the engine is spinning.
This is the confusing part. Both of my other generators, the gov arm extends on both sides of the gov. And there's a spring at the end of it, (opposite end of the throttle end of the arm) that's connected to something solid. That's OEM.
On this one, that spring is on the same side of the gov. that connects to the low idle arm. So if the governor itself is supposed to keep the engine from over revving, why put that spring on the same end of the throttle.
I'm gonna try bending (shortening) that heavier spring today. If that doesn't work, then I'll lengthen it. For the life of me, I can't wrap my head around that being the solution.
As @bertsmobile mentioned about the tension on the gov. arm, and holding it with my finger, it's easy to hold it in place. And I can feel the arm pressing against my finger towards the higher idle.
The governor gear with the flyweights inside the engine is what slows the engine down. The spring speeds it up. If the governor gear is set correctly in its static setting, and isn't working then I would say the governor gear inside the engine is broken. It looks like static setting on this engine would be with the rod going inside the engine to make contact with the governor gear should be turned all the way clockwise until it stops.
Yes you can put your finger on the throttle rod and move it back & forth but you can not use the engine in that state
A check for an internally defective governor is to remove the rod that connects the throttle & governor arms.
Start the engine and work the throttle with one hand while feel the governor moving with the other.
If the governor moves in responce to the engine changing speed then the governor is functioning.
What most do wrong is to think that the governor makes the engine go faster.
It actually makes the engine go slower.
So at 0 revs the governor axel should be in the flat chat position ( throttle wide open ) so as the shat rotates it closes down the throttle.
Most common mistake is to clamp the lever on the shaft so the only way it can turn opens the throttle.

And replace the crankcase gasket and seal
What happens if you loosen the clamp on the gov arm to it's shaft, and move the arm to the point the carb is wide open, and while holding that there, turn the gov shaft as far as it can go in that same direction, and then tightn the clamp? Thatbtakes all the slackmout of the linkage, and not sure if you have tried setting it up that way or not . . . .
That rod would be the governor shaft which is what the gear and plunger ride on.
Can't speak to a Chindra, but on the Hondas I have been in, the clip that holds the arm with the paddle in the block interfaces with a casting flange that limit's it's rotation. For that matter, I can't imaging how that arm would gibe clearance for anything to depart if tne gov linkage it set correctly (assuming you have the correct gov, and not just 'close' . . ).
Again, I suggest you contact the mfg. and verify . . .
The limited range of motion of the rod when the throttle linkage is setup correctly may well be used as the retainer. As I noted prior, on the real Hondas I have worked on, the clip that retains the gov rod in the block also enforces hard limits on it's range of motion.
Looking at the exploded view of a Honda GX, I see the same - no retainer proper, but the same hairpin clip on the gov rod on the outside of the block, that typically indexes a flat side on that rod, and is limited in rotation by a raised boss on about half the diameter of where the gov rod exits the block: https://www.planopower.com/oem-part...ARREL/GX200-JPN-HX//A/2410ZK001AZK00E0300BC/y
Or a service manual for a Honda that should be very close - review section 7: https://www.google.com/url?sa=t&rct...GX160_SM.pdf&usg=AOvVaw3R38sJOynsJmDifC5eMkya
It's possible that your springs are wrong, or in the wrong holes, causing the gov to expend far more than it should . . . and the surging is another indicator that the linkage may be setup wrong . . .
Not sure if your Chindra is totally like a Honda or not, but on a Honda proper (as per the service manual) the clip that holds the paddle arm in is to have the flat side sit in the notch in the shaft, and then it contacts to block casting to limit movement. Not sure if the knockoff paid that much attention to detail . . .
Finally getting back around to this generator. I've been watching a few video's of bypassing the governor with a direct throttle cable. The procedures on this, looks pretty simple. Just wondering if anyone else has done this?
This gen will be used only for power outages. Once the necessities get plugged in, they won't change much (except for the fridge compressor). So setting the throttle to a good RPM should be ok. Right?
Won't work
The output of the generator must be matched fairly closely to the demand put on it .
When the fridge is not working you will be over generating so unless you have a system to burn off the excess power the generator will short internally & burn up.
The actual power grid uses massive resistance heating coils inside the water supply of the power stations to balance the grid becaue they must always have excess power on hand to compensate for things being switched on & off.
Small gen sets do the same by varying the output to match the demand as close as possible.
This is the big problem with roof top solar and the real reason why electricity grid owners hate them.
Things with motors in them like old style fridges, freezers washing machines etc can handle it but anything with an IC board can not.
So modern "smart" machines tend to fry the control circuits which is why you store the DC in batteries then use an inverter to convert the DC back into AC which seems really stupid when you first look at it.
I am about to rewire the house either 6 or 12 Volt DC and use auto LEDs for all the lighting direct off the batteries.
Sounds like governor hop due to over sensitivity. Is there more than one hole in the governor arm that will accept the spring. May need to make a position change to reduce sensitivity.
You hit the nail right on the head. Thanks man. This darn thing is done.
Other crap that got fixed on this:
New fuel tank, rebuilt carb, cleaned and tightened the 110 plug. It was corroded, and so loose that anything you plugged into it, would just fall out in like 5 seconds.
Repaired the mounts. recoil, Air filter housing, Still got got get a new oil sending unit.
I'm glad to be done with this. More more glad of the knowledge I got from this project.
Thanks again for everyone's advice and links.
When I get a genny in with a loose AC socket, I replace it with a waterproof one that takes a plug with a screw in locking ring.
Then I make up a short lead with the screw lock plug on one end and a standard socket on the other.
The other trick that works really well is to fit a cable clamp near the socket so the vibrations do not cause the plug to fall out.
A loose plug is really bad for the generator as when it is just making contact you get both a high resistance joint and rapid make & break which sends the governor into a freenzy.
Glad to hear that you got it done!
Illegal to do here but if you go that way make sure it is clamped very tight to the genny frame because the wire will work harden then start to brake .Funny you should mention that. My brother and I was talking about this pig tail he made a few years ago that needs a new plug. I asked if about wiring it in directly to the Gen. It's about 2ft. long.

Thanks man. This my first time to replace all the contents that make up a gov. I already had about $100 in parts, (tank, carb, now 2 gov's). Plus a lot of time repairing the mounts. And a boat load of cleaning.
It was interesting to say the least. And very frustrating at the same time.
Illegal because people chuck them around, the loose wire gets mangled then you get zapped when starting the genny.
Where as a short lead with a plug at both ends generally gets removed from the genny when it is being moved around.
A bit different down here.LOL.. Not to get political, but the government does have a way of trying to protect us from ourselves.
If you want some confusion deal with US 110/220 volt power and portable generators. Some have 3 wire output some have 4 wire. Some have a ground lug some don't. UTUBE is awash with idiots showing how to incorrectly hook a portable genny to a house for backup power. There should be a test to be able to shop in the electrical aisle at the home improvement stores.
I can’t count the times I’ve had a portable generator come in after the owner has adjusted the RPMS and had tools burn out. 90% of people don’t know that there is a thing called hertz, which is affected by the engine speed. You must adjust 110V to 50 hertz and 120V to 60 hertz most of the time, but not always. You have to look at the ID tag, as some units coming from overseas are different. Had one customer burn out his radial arm saw and two circular saws, plus portable radio and couldn’t figure out why. Unit was adjusted to 3500 RPMS, 110V, and 72 hertz, constant speed with no idea down. Even the wires were melting.
Some people will refer to hertz as cycles. And most portable gas generators due to what is called governor droop will run around 3750 rpm which creates about 62 hertz/cycles. When a load is put on the generator the engine should run closer to 3600 rpm which creates 60 hertz. This is true for what is called 2 brush generators, Some will have 4 brushes, which will turn 1800 rpm for 60 hertz, think bigger stationary gen sets,All of that is talk about "hertz" is greek to me. Thanks for the info. I gotta start doing some research.
But wait!........ some guy on the internet told me you can get more power out of your portable generator by bending the thingy to make it run faster and it will make your 6000 watt generator a 7000 watt generator. Whatever a watt is. It's on the internet so it must be true. ?
