Hi. I have a EU7000is generator that is 5 years old with roughly 200 hours on it. Oil is changed regularly. Fuel is always fresh and/or stabilized. Battery is fully charged and nearly brand new.

Up until recently, the generator would start up and run flawlessly. Recently, I often run into an issue when I go to start it using the push button, it tries to start up but it won't turn over. I hit the start button, it tries to start it for a second, and then nothing. In those circumstances, I open the side door and try to manually start it only to find the manual pull extremely hard to pull, almost as if the motor is stuck. If I try to pull it (firmly but gently) a few additional times, I can feel the motor turn a little, the pull motion loosens up a bit and then I can start it manually (or with the push button). From there it runs perfectly, will power my house for days without issue. Subsequent starts once warm don't seem to present any issue either, the unit seems to fire up right away.

Any thoughts on where my issue is? What are the things I should be looking at that would cause the above? Thank you in advance.

set the valves first.

then replace the battery!
yea a battery issue does this!
lol been there done that!
we use HD batterys now in all of the eu7000is gen sets.

do you have a trickle charger on the battery??
it is a must for these sets as they have a computer on board that has memory.
click here for the battery charger page
we use the solar brand 1002
it fits inside the battery cover above the battery.
and there is a knock out in the cover for the charge cord for 120 vac in to the new charger.

check your compression.
it should be 60-90 psi.
make sure they valves are set perfect.
if it is higher on the psi
you are looking at an engine full tear down to look at the cam assy.

Hi! I did replace the battery and it did not solve the issue. And yes, the battery is plugged into a trickle charger at all times. The battery is strong. Just feels like there is something that's preventing the motor from turning over in some positions but once I softly pull the pull cord it loosens up and I can fire it up easily with the push starter or pull cord. It's strange. Not sure what you mean by "set valves first" but i'll do some research on that now, please elaborate if you can. Thanks!!!

any small engine try to leave it on the beginning of the compression stroke.
easy to do with the pull rope.
that way the valves are closed.
a depressed valve spring is a bad deal over time..
it is that metal memory thing.

as well as trash can get in through an open valve.

Never have done that. How often should it be done?

after every run.

ty tab.
it has been a mad dash here getting gear ready for the end of the year.

replace the battery!
bad cell!

 

[iowagold]

any time!!
lol!
been there done that on the batteries!
yea we like the little solar brand charger.
pm me for a link.
they fit perfect just above the battery on a honda eu7000is!
we leave them plugged in 7/24 and get 4-5 years on the batteries.

we are looking in to the lithium batteries for these gen sets...
so far they are pricey. but they last 10 years or more.
the prices are dropping again on them.
the good thing is they work in temp extremes,,,
the moto cross and circle track guys sear by them as they are super light weight.

My eu7000isAT 89 hours. Exactly the same problem; push start button, clicks but won’t turn over. Push 2-3 more times it starts. Replaced batter. Nope. Same problem.

full charge the battery before use.
if that does not work
replace the battery again.

make sure to use a quality charger maintainer for the battery.
the onboard battery is only good for 2-3 starts after that it needs to be full charged before starting again.

no on the xx 40 weight on a honda generator
now a 0-30 is a good plan for cold winter.
and change to a 10-30 in the summer.

and yes a block heater works well on these gens if they are stored in the super cold

best is a heated generator shack at 50 to 60 deg f
that way the air is heated as well.
