Question about Yamaha EF2400iS Portable Generator

1 Answer

Ejecting oil I started my generator after it was sitting idle for an hour or so and oil came leaking out the bottom. Maybe half of total oil. I refilled and started it again. Sputtered a little and is now working fine. Could that oil have come out the crankcase vent or.....?

More than likely it came out of the crank case vent. Your intake valve could have been stuck open (for some reason) which pressurized the crank case.

Rough idle on 99 chevy metro 1.3l engine. changed plugs good pickup but intermittent misfires. even when idling. also leak in exhaust system.


First thing, fix leaking exhaust, this can cause erratic idling...second thing, remove and clean IAC valve and MAF sensor..dry and replace, also try putting some SeaFoam in the petrol, engine oil and air intake, let sit for 10 minutes then go for 10-15 min drive...suggest you change engine oil shortly after driving about 5000kms, if the oil is old..

Did you get any codes on the misfire? If you did not, test ignition coils, test vacuum, test fuel injectors, verify correct plugs..That's right, anything from a fouled spark-plugs to burned cylinder head valves can cause a misfire. Whatever the root cause of the misfire, the bottom line is that one or more cylinders are not contributing to total engine power output. This leads to power loss, rough idle, unstable RPM and bad gas mileage...cheers

At idle, why does speedometer show about 5 or 6 miles per hour and the odometer shows the mileage going up while sitting still?


Could be a bad instrument panel(IP). Rough idle in gear could be a vacuum leak. Maybe a tune up.

What can i do to find out what is wrong because i turned my generator off and about 3-4 hours later i turned it back on and it is not putting out about half the voltage.


Only Suggestions .
control any slidingcontact in the electric field .
If the engine has the other lower rpm after the use maybe A canister cold spray can give a result if you spray on voltage regulator or other parts of the electronic ?

-------------------------------------------------------------------------

Other posibility can be sludge inside the oil carter that will have pistons with blocked oil control pistonrings if they sitting full of grey sludge that will heat the motor, how old is the oil ? if there is enough oil inside.
disconnect the oil protection circuit if that was also in good condition
to get differend behavior of the output.
sludge in airfilter float chamber or nozzle .

It will start for a minet then shut off and wont start till it sits for a half hour


Check to see if the fuel filter is clean or change it. If the screen in the bottom of the gas tank is clogged, that will do it too. If those solutions do not work, check the oil level and condition of oil, if it is low or dirty the low level switch will shut it down.

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.
