Honda 3000 Watt Portable Generator - Page 4 - Answered Questions & Fixed issues

is the battery charged

check the battery?

check the ' auto start ' voltage sensing fuse. replace the fuse if it is bad.

What is wrong with your unit? Typical repair places would be a lawnmower shop or chain saw shop.

Do a deep clean of the fuel ;lines,carb,filter and tank.donot coat the tank inside,if is too rusty try find a used one and also change the spark plug and do ahead clean.

Change the spark plug!

Hi there,

If I remember correctly this model does not use a fuel/oil mix. Please confirm this.

If what you are saying is that in filling the device with gas and checking the oil level, both overflowed, then we are good.

As you have done, drain both to their proper levels.

Now pull the spark plugs, they are most likely fouled with oil.

Turn the generator over a few times to clear the cylinder of excess oil.

Give the plugs a good cleaning. You may need to replace them. I just have a thing about tossing something with life still left in it.

Put the plugs back in and fire it up.

Best regards
Mike

Chokes are used to draw gas through the center jet to run. If the choke is not working properly and it is not closing all the way the engine cannot draw gas through the center jet and will not crank.
Your problem is just the opposite of that
Yours is getting too much air so that is why it runs only with the choke closed
You will see two set screws with springs attached to them. one is for fuel adjustment and the other for air mixture. Try adjusting the two in all the way and back off 1/2 turn each then try and start it. If not firing look at this website below and click on the video to view how to clean out the jet

Hello. There are a couple of reasons why a battery goes dead, the most common one being that there is a drain on the battery which has to be located and fixed. You can upgrade the battery as long as you are sure that the voltage on the new battery is the same as what you have now. The new battery will have more amperage which simply means that is it indeed "bigger".

What you need to do is first remove the new cord that you installed.
(This next process is best performed by 2 people)

Pre-wind the spool gently COUNTER CLOCKWISE until the spring prevents further winding. Have the 2nd person grip the spool so that it does ot unwind. Back off the spool until the re-wind rope hole is aligned with the outer cover rope guide. Insert the new rope through the outer cover rope guide hole and into the spool hole. Pull the new rope through the spool hole and tie a single small knot. Pull the knot into the hole. 2nd person releases the spool and the rope will rewind into the re-coil assy.

Recheck for spark when it stalls. If you have lost spark I would say a heat damaged coil.

You should also drain and inspect the carb bowl. You may have low fuel flow which limits full throttle operation to 30 minutes or less. When it dies you are just refilling the bowl for the next run.

Good luck and be careful!

Hi and welcome to Fixya I am Kelly. This symptom is typical of fuel starvation. It can be caused by

1. A dirty fuel filter (if installed)
2. Debris in the bottom of the fuel tank
3. Fuel shut off selector not all the way on or debris in pet-c^ock bowl. This is located on the bottom of the fuel tank.
4. Float needle assy not allowing proper fuel flow in the float bowl
5. The fuel supply line or the plastic "Y" just before the carb is cracked and air is being introduced into the system as the fuel hose swells from heat.

I really think you have a fuel supply issue. A break down can be found here of your carb:

Fuel tank cap removed

You should be able to remove the angled drain screw (Item 6 above link) in the bottom of the float bowl and have fuel flow freely out of the hole. (I use spray paint can cap / lid to catch the fuel. If you can not fill the spray paint cap to the inner circle of the cap in one continuous attempt there is a problem with fuel supply ( 1 - 5 above )

If you can avoid it DO NOT remove the carb. Getting all the linkages correct during reinstallation is tedious even for seasoned techs on this generator. You can safely remove the float bowl and check for debris / give the jets a blast of carb cleaner. If you do use carb cleaner also direct a shot into the fuel hose connection (hose removed) on the side of the carb with the bowl off. The jet is in the very bottom of the center post.

PLEASE do a leak test before starting the engine with the fuel selector on. (Safety issue)

Make sure you replace the fuel tank cap before starting the generator.

Thanks for choosing FixYa.

Is there enough oil in the crankcase? Many generator ignition problems come from the oil level sensor. Either not enough oil or the sensor being bad.

Well, only 2 things, is it getting gas?? Is is getting spark?? Squirt some gas down the cylinder and see if it will fire. Yes? No? If it fires, but won't run, the carb is messed up, or the fuel is not going to the carb. Then check the spark with the plug resting on metal and connected to its wire. If you have no spark, that is what you have to chase down. Sometimes these things sit and the contacts on the alternator rust over, (iron) and don't develop any juice, they have to be cleaned, the coil could be shot. The Carb might have been cleaned, but is it clean? Those jets are finicky. And gas that sits turns into rock. Check it out. Hope this helps.

Here is the link to download for your particular model from Honda"s website. You may want to get your serial number to refine your search. Good luck and safety to you....

That will depend on your specific model and use environment.
You should be able to find the user manual for it here, however:

I would guess though that 10W-30 would be suitable for most normal circumstances.

HONDA MAKES LOUSY CARBS:
Remove the Carberator from the engine...You need to inspect it.
Remove the carb bowl and clean it.
Remove the Float and clean the valve seat seat.
Blow thru the fuel flow areas and see if plugged.
Note: A PC compressed air can works well for this.
There is a steel plug going up to the center of the carb venturi.
This plug get plugged a lot! rust is the problem!
Use a very tiny drill less than .010 Dia to check for rust.
Insert from the bottom up and see if it comes out in the venturi.
If not, you need to hand force the drill upward and clean it out.
Soak everything by spraying carb cleaner in all openings.

note: DO NOT TRY TO REMOVE THE RUSTED PLUG. CLEAN OUT THE HOLE SO FUEL CAN FLOW INTO THE VENTURI. DO NOT DRILL IT OVERSIZE.

Re install the carb...90% of all Honda engine problems is the same.

Hi. There are 2 things that control the Auto Throttle and that is the idle control valve (Connected with black and yellow wires) and the Auto Throttle Unit.

Start Generator
Check for 12VDC on the Yellow wire of the idle control valve. Yellow is positive to any good Chassis ground. If you don't have 12VDC then either the Auto Throttle switch is bad or the Auto Throttle Unit iself.

You can gain access to the Auto throttle switch and again check for 12VDC to Ground on both sides of the switch with the switch on. (It may read as high as 13.8 engine running) If you don't get 12 - 13.8 VDC the the Auto throttle control unit is bad

If you have 12VDC to the Idle control Valve and it does not work perform a resistance check across the coil of the Idle control Valve (both wires disconnected Engine off) Black to yellow should read 3 to 4 Ohms If you have no resistance then the coil in the Idle control Valve is bad.

If you need more help just respond here

Make sure the breaker has not tripped. If the breaker has not tripped then it can be many things causing it not to produce power.
