Question about Electrical Supplies

2 Answers

I have a EF3000iSE Generator Yamaha. I am unable to get it started.

I have cleaned the carb jets, checked the float, battery is good, have spark, etc. If I inject fuel into the carb manually it will start but won't start normally, any ideas?

Carbureror is plugged up... likely it sat too long unused, with gas.

See exploded view of carburetor.

Be sure both jets are clear. Remove the jets and spray carburetor cleaner into the jet seat and it should flow out the emulsion tube and the tiny holes in carb throat near where hrottle plate makes contact.

You have carb passages that are still clogged up. when you do get it all clean and running always use a little seafoam in your fuel. it works very well on small engined units... a few ozs in 5 gallons is plenty and stores very well also.

3000 watt yamaha generator is really hard to start and when started it stalls under load.


sounds like the carberator needs cleaning and the linkage that makes it open up under load. it works off the flywheel. a lot of generator problems are gas related. water, trash and varnish build up in the carb.
