Question about Honda 6370C - Parallel Power Kit For EU3000i

6 Answers

Honda EU3000is generator will not start with electric starter.

My Honda is only a few years old, and has 15 hours of only test use once per month. Gas and oil changed once per year and sta-bil added. I went to start it with the electric start and heard a loud noise as if the starter motor is seizing up. Use of the pull start works ok. It runs good but I am noticing surging speed when running. Any suggestions to what may be the problems on a generator that is like new and has never evan been used under load with only 15 hours of test use?

    My generator is about 4 years old with alot of hours on it. Between camping and loaning it out the generator rarely sits. I noticed it took longer to start on my last trip. It is now time for my next trip and it won't start with the key at all. However it starts with the pull start no problem and runs normal like it always has.It will crank over with the starter motor just fine, but won't start. I made sure the battery was charged and tried again. Still won't start. I tried bypassing the ignition switch and that didn't work. Short of blindly replacing parts till it works I don't know what to do next.

    You need a new starter relay box (Black) behind the face plate on a rubber in back of your generators battery charge unit....

I'd say your battery in the generator is going bad or bad. They are very small and do not hold a charge for very long. The noise you heard was probably the starter shaft hitting the flywheel cogs. I doubt any harm was done as long as you did not repeatedly try to start it with the key. Why Honda put a battery in these is because they are intended for use in a campground setting, where they would be used on a daily basis and the battery would constantly charged. Whereas people like us buy them for emergencies only, they sit for long periods, and the battery goes flat, and the fuel clogs the carb and we get the surging issue. That's my 2 cents. When I brought mine home new, I Sta-bil'd the heck out of the gasoline, this past winter, on start-up, the unit surges. Of course the battery was flat.

    The battery is dead get a new one. It sounds terrible when the battery doesn't have enough charge.

The Honda EU 3000 is supposed to be able to handle steady use without any problem, however, this is not always the case as you have discovered.
The unit will usually key start as long as you pull the choke out. As you mention, it will always start with the pull cord. On mine, shortly after the battery started giving trouble and I used the pull cord, it snapped. When I took it apart to fix it, I discovered that Honda had kindly left a nice razor sharp metal edge right where the pull cord goes through. The dealer wants something like $200 to fix this, and while it is a long job - something like 2 hours - it isn't difficult. I filed down the offending metal and it's OK now.
The worst problem with these things is water that gets into the carb. Some of it may be introduced vie the gasoline, but some is from condensation, which there is little you can do about.
You need to take the carb off and clean it, plus replace the fuel filter every time - and the spark plug while you're at it. At some point you might find that the bottom of the float bowl has actually rusted. Put a new one in.
We use ours every day as the backup for our solar system. In the winter, there's not much sun, so the genny is used daily. In the summer it may sit for several months untouched, but still starts OK most of the time.

The problem with the surging is from the gas line being restricted from the old gas. I fixed mine by putting gumout in the tank with fresh gas. You have to then play with the fuel cutoff valve as that is where it usually gums up. You get it started and run it and then turn the valve off and let it die. After several times, the generator will run fine without it surging on the eco-throttle.
My EU3000is is eight years old and sits outside and is still fine. The only problem I had lately is the battery is dying and the pull cord snapped when I tried starting it manually.

On this unit, the pullcord and the starter uses the same flywheel engagement mechanism. So, the starter to flywheel cogs must still be intact. The starter pinion gear might be the problem
I had to replace the drive mech when it exploded. They updated the drive and I couldn't get the part I needed. The new drive mech assembly was $300! I found a used one.
I have NEVER been able to get my unit to start with the starter. It always start one the first easy pull! It turned over like a champ, but no start......go figure...
I recently bought a new replacement eu3000i, as the old one just bit the shed. It siezed up. I haven't taken it apart yet to know for sure, but it went clacka-ckacka-WONK!, and the pull cord won't pull.
BTW, I love those gensets!

89 f150 will start but after choke let's idle down it dies or if you even touch the gas. It had sat up for 5 years but the first time I got it started it drove for over an hour.

The damage is already done. Gasoline breaks down within 1 year. Drain and flush the old fuel out of the gas tank(s). Try adding Chevron Techron fuel injection cleaner to the replacement gas. That may work. However, you probably need to remove all the fuel injectors [if it's a fuel injected engine] and have them sent out to be professionally [ultrasonic] cleaned and tested. Fords are notorious for fuel injector problems. Also do a fuel system pressure test, as the bad gas may have damaged the electric fuel pump [located in the fuel tank(s). For a carbureted engine, you will need to have the carburetor overhauled or replaced with a rebuilt unit. NEVER let a vehicle sit unused for more than 6 months without first treating the gasoline. I always add a fuel stabilization product like Sta-Bil to the fuel, if the engine will not be run for at least 2 months or more. Adding these products after the fuel has gone bad [is already old] will not help. Then it's to late. Below is a link for Sta-Bil. I've used this product for over 20 years. It will save a LOT of grief, when storing vehicles or gas powered lawn equipment. See

2007 honda crf 250. Sat for 1 1/2 yrs. won't start by cranking, or pushing.

Try a small shot (about a 2 second spray) of starting fluid in the air intake then cranking....

If your bike fires and runs for a bit, the most likely problem is your gas has gone "sour". You need to drain all the old gas out and properly dispose of it.

Over time, gas will cause a varnish buildup in your carb if it sits too long. You can try adding some carb cleaner to fresh gas, but the results will not be immediate. You may have to have the carb rebuilt.

When you store anything gas powered, there is an additive called Sta-bil that will act as a gasoline preservative for about a year.

Will be gone for over a year and don,t have anyone to move or start it what can i do to keep it in good shape while i,m gone?


You can buy a fuel stabilizer, Sta-bil, and add to the fuel tank. This will keep your fuel from gunking up in your fuel system. Start and run your bike, after adding the Sta-bil, and let it run for a few minutes to get the Sta-bil throughout the system.

Change the oil and filter, change your clutch and brake fluids and remove the battery from the bike.

Place the bike upon something to get the wheels off the ground and cover the bike with a tarp or bike cover.

Give your gear oil a look, but it should be OK for that length of time.

Some people drain the gas out of the system, but if your tank has any inside damage, it will begin to rust and you will have to clean the tank before running the bike.

The bike sat up for a while. It smokes quite a bit when cranked, smells like gas initially which may be because choke is on, but eventually smells like smoke. only 4k miles. Is it rings, valve seal...


Anytime a bike sits for an extended period of time, it is a good idea to drain all the fuel out of the system and add Sta-bil when filling up with fresh fuel. Also, the rings and seals need time to re-seat themselves. This could take, up to, three days.

You should do an oil and filter change.

After running a tank through, with the Sta-bil added, the system, buy a can of Sea Foam and add the recommended amount according to the directions.

This should clear up the issues you are having.

I ahve a 1989 Chevy Suburban and for the past year when the gas gauge reached 3/4 tank I filled up with gas (Regular) and I let the Suburban set up for two moths and I believe the gas went bad. I screwed...

I would first get the fuel filter changed and see what this does
also you may have to get rid of this tank of fuel if the ratio is too bad from the sta bil
you may also want to change the plugs and have the injection system cleaned if this applies if not get some carb cleaner and clean it really good ok and this should get you going like it should
hope this is very helpful for you

Bike has set for about a month. New battery was 4

Your battery looses about 1% per month sitting. Shooting 50 amps into your little battery didnt do it any good even though you felt better. You might have a dead cell but I doubt it in a 4 month old battery. You can do a hydro test on it (good reading is 1200) and a volt reading (above 10 is ok) or maybe just replace it.

I suggest you put it on trickle charge for 24 or more hours.

If you regularly let your bike set for more than a week, you may want to consider adding a fuel stabilizer which will prevent or at lease reduce the harmful buildup of varnish and other gunk in your fuel system. I like Sta-bil but there are others. You might inquire at the Honda shop what they recommend. You might also want to use something in the fuel to clean the system - popular is injector cleaner but I am not personally endorsing this. Ask the parts guy at your Honda shop.

I hope this helps you ...

Positive commentrs always welcome

Mcculloch 310 oil mix ratio

The proper gas/oil ratio is 50:1, that is 50 parts gas, to one part (2) cycle oil.

If you plan on leaving gas in the tank when not being used, I always recommend adding some gas stabilizer, such as Sta-bil, which makes starting the chain saw easier regardless of how long the fuel mix has been sitting in the tank or saw (up to 2 years according to Sta-bil label)
