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 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.

Generator was running, ran out of fuel now wont start. Getting fuel but doesnt have any spark that i can see. If you hold the plug and touch the unit, can feel a mild shock.

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!

Clean the contacts of the battery first with contact cleaner or simple soda, check the carbons of the start motor, air filter and fuel filter, fuel filter might be stuck.. u might change it, use a carb cleaner to clean or unclock the carburator.. try all this hints first

Start the engine

I assume you refer to a 6500 watt Honda, if it's electric start/and manual(pull cord) First supply a 12 volt battery /if you haven't put fresh gas in it do the best you can to remove all the old gas from the tank and you should find drain screws and small hoses on the lower part of the carburetor. After completing this step add about 1 gallon or so of fresh gas, remove the air filter system from the face of the carburetor ,with a small squirt bottle put a tea spoon or so of gas into the of the carb, close the choke and turn the key, if it fires let it run with the choke closed for only a few seconds then slowly open the choke fully, if the engine stalls close the choke and start the engine again do not leave the choke closed for extended periods as this will cause engine flooding and spark plug failure. Also be sure you have inspected the existing spark plug to be sure it's clean if there is any question about the plug change it.

Honda eu3000is. Run rough until i pull out the choke about half way. Then runs grear. It has done this since it was new. Now about six years old. It has low hours. I just cleaned and rebuilt the carb...

You didn't say whether you were using old gas or fresh or whether you were using ETHANOL gas but It sounds like a bad gas problem. Get some fresh, high test gas and try that

EM 3500 Will start, then stalls after 30 minutes, starts again and continues to staff after 5 to 10 minutes. Oil is fine.

With regrets, I do not have any personal experience with generator troubleshooting. However, I have been informed by some people that have good experience with them that a generator needs to be run for a couple of hours every month to keep the system in proper order. Should a generator sit idle for ten months, the fuel can actually "shellac" inside the carburetor and lines. This will then travel to areas that will gum up - thus the necessity to drain the tank and carburetor completely.
Here is their advice:
Your service person(s) may not be aware of the time the unit sits idle, and if they are aware - then they are not giving you straight facts (in my opinion). I would suggest contacting Honda customer service directly, and explain this situation to them - they will probably be more then happy to have a technician assist you properly. Contact the 'customer relations' number, and they will direct you from there. Here is the link:

I am sorry I couldn't be of more help.

I have a 5 year old EU300is that would not start with or without the battery. I went through all the usual such as gas, plug, oil, etc. The battery showed 12 volts, however, when tested further it would not hold a load. I bought a new American made battery and now the unit runs fine.

I have a 3000is not starting. Has gas spark oil.

Use fresh gas! Dont just pour some on top of the old...Change it out.

Drain the carb bowl (Honda carbs have a drain screw slightly off-center of the bowl bottom).

The Honda EU3000is uses a vaccuum-operated fuel pump and old gas will ruin it also.

Take the fuel supply line off the carb inlet, direct it in a container and spin the engine over. It should pump a stream that is FULL LINE DIAMETER.

If still no start, take it to an AUTHORIZED Honda Power Equipment Dealership.
Find one here.

Hope this helps.
