You Sir are so good at fixing generators they named a Hurricane after you. Seriously thou safe travels to your friend and good on him for helping out.

[@IndRepair]

Ha! I hope he is safe while there for sure! 🙏

This is a good lesson in never assuming the first issue found with an engine is the only one. Battery connections, emulsion tube, solenoid plunger! 🔧👍

[@IndRepair]

For sure!

Great video! I’ve been struggling getting my Yamaha inverter running after Helene. She quit running. I’ve been going through it, exhaust was clogged and took care of that. Still won’t start so the fuel lines are now new, but now it’s time for some of the details shown in this video. Hate to quit inverter, it’s been a great machine. Thanks for methodically going through this. Good craftsman-like video. Appreciate you!!

[@IndRepair]

Thank you! I hope you are able to get it all back up/going!

[@Rein_Ciarfella]

Only one minor detail missing, Martin - make sure the bowl O-ring goes on correctly so it doesn’t leak.

[@IndRepair]

Definitely!

[@Big_Johns]

Luckily that emulsion tube fell right out, most of the ones I get to work on have to be beat out with a jack hammer. 🤣 Good job brother. 👍

[@IndRepair]

Yeah for sure!

[@IndRepair]

Thank you!

[@Big_Johns]

Anytime bud

[@gillgetter3004]

Wish I could find one for 500. I’ve found those selinoid plungers stuck too, many times👍

[@IndRepair]

Definitely!

[@philliphall5198]

Love these units 😊

[@IndRepair]

They sure are powerhouses

Great video! I have the EF6300isde that has a slight surge, more noticeable running in eco mode. Do you know if they use the same carb? Also I don’t see the pin retracting on fuel shut off solenoid (pin seems to be staying out all the time). Could this be causing the surge? On to checking the jets? Thanks in advance for the reply.

[@IndRepair]

Not positive if it has the same carb but the solenoid should definitely retract. I would check this and the jets

[@joecrozier4922]

@@IndRepairappreciate you!

[@matthewcaldwell6763]

Does that carb have emulsion tube? Or is the bowl nut the emulsion tube?

[@matthewcaldwell6763]

Spoke too early

[@IndRepair]

Definitely

[@IndRepair]

I hear that one

[@crisprtalk6963]

Hey Yamaha.. we do NOT need solenoids on the bottom of carbs in generators!

[@IndRepair]

Definitely see them on almost every large one anymore!

[@Rein_Ciarfella]

Major design flaw - not having direct access to oil level check without having to remove a side panel requiring a screwdriver. Every engine should be checked for oil level every time before starting! I could easily see this generator engine being destroyed because the oil level wasn’t checked religiously.

[@IndRepair]

Definitely!

[@Ram14250]

Great job, but that oil was not great. Looked used and sooty. I would of changed it!

[@IndRepair]

For sure! Not the reason it didn't run though

[@TLeightonWomack]

Looks like more than 61 hours on it.

[@IndRepair]

Yeah bad shape!

[@crisprtalk6963]

construction use, probably sat in back of pickup and got banged up good.

[@IndRepair]

I see some that are brand new look years old when this is the case. I am sure you are correct

[@lylemader8035]

Only a hack puts a spark plug in without checking the gap....

[@IndRepair]

Lol

[@goofe.washington953]

A hack? You must not watch many of this guy’s videos. He is far from a hack, and I doubt he would have a successful small engine repair business if he wasn’t good. Watch some of his videos, so you can post more informed comments.

[@IndRepair]

Gap comes standard as .031" on these. If you think the spark plug gap matters in a small engine watch the video at kzbin.info/www/bejne/oIvYYXqdf951jNE on this issue and see what the results are. On a car it is much more critical or this, yes
