Generator Engine Dies Out Quickly - Only Runs for a Second (Not the Oil Sensor)

Found this 10000 watt Gentron generator on Facebook Marketplace for on $150. According to the seller it starts on starting fluid but dies out quickly. He bypassed the low oil switch, replaced the carburetor, spark plug, air filter and other pieces and still it only runs for a second. Let dig in a see what the issue is.

Generator Model: GG10020

I use Harbor Freight Super Heavy Duty Degreaser in my ultrasonic cleaner.

James, one of the things that sets your channel apart from the others is how you take the time to show exactly what's wrong. For instance, putting us in view of the exhaust to hear what was troubling you. Others would simply say there's a noise and begin to fix it. BTW: Your solution for the spark arrestor was excellent as was the rest of the video!

I repair generators part time for a shop down the street. After a storm like we just had in florida, after people ran their generators for a week or so, many come to the shop with the same running issues. And yes, its that crappy spark arresting screen. I could charge each customer a hundred dollars shop time for the repair and make a fortune. But I tell them to remove the screen and try it before they bring it in. It doesn't help my bank account but I can't rake people over the coals on something that simple to correct. Cheers and Merry Christmas to James and everyone out there.

Thank goodness that there are still meticulous craftsmen like you who have a passion for repairing mechanical devices. We who are not "handy" salute you! 👍🐻🇺🇲

Clearly this generator needed someone with attention to detail, luckily you found it and gave it another chance to make power for someone, nice job

As our temperature is headed to the negative (F°) it was great to see a warm video.

K, so this has literally become one of my fav channels.. I am an Electrician, but have been looking at doing small engine repairs on the side, just to make some extra coin... This channel has been incredibly informative, and I wish I had found this channel several years ago when I got rid of my 1960s Lawnmower that had a crank no start condition, but would happily run on starting fluid..

[billjones]

I know you posted this awhile back. I want to say thank you.

Our Predator 6500 just stopped running.

Would start and chug for 15 to 20 seconds and Die.

Replaced Carb a d related. Components. Air line on tank. ( it was split). Cleaned tank.
Was close to giving up.
Came accross your video.

We pulled spark arrester/s. Outer only had a few specs. Then seen how a. Inner one came out.
Removed. Started generator.
Ran great after s few seconds of blowing itself out.


Saved me from having to replace generator .

I just wanted to give thanks to Jesus for leading me to your video and thank you for it's content.

I love your inventiveness James. These types of hourmeters come in DC types and AC types, as you said. Yours is obviously one of the AC types, as you also said. The instrument counts up with the presence of an input voltage across the input wires. There are three standard AC supply voltages provided by the manufacturer. Those are 24V AC, 120V AC and 240V AC. The instrument should be marked with that appropriate for that one. I am presuming that they have provided you with one of the 120V types. All you need do is to check that the input voltage for your meter is 120V and remove the broken hourmeter from the panel. You will have to wire the input wires onto the hot side of one of the legs. Seeing as you have already paid for it you may as well use it, This can also be a cheaper solution to paying Generac $40 for one of theirs in future projects.

Wow! What a steal for $150 dollars. That machine would run my whole house, no problem. My Gennie didn't come with a spark arrester, but then I don't live in a dry area.
Also the decal on the recoil assy. looks to be crooked, someone clocked it to the top position. Nice vid.

Of all the small engine videos I've watched on YouTube, I believe this is the first one with a 4-cycle engine with a clogged spark arrestor. I've seen it enough times on 2-cycle equipment, including on my better-branded line trimmer. This is a good one to remember...

[brendandrury]

I saw you using a couple of types of lifts to raise equipment. It pleased me. I wish you had a high table of 3/4" plywood that you could set the machines on. We don't think our backs will go until someday a disk squishes out to the side or to the posterior. Then you are screwed for life. I know this is off-topic but I bet you have hundreds of subscribers who can relate. Great videos.

I love watching you work. I know a little about engines, but not enough to do what you are doing. Just watching you troubleshoot and fix multiple problems is very satisfying.😅

[walkingthruyourdata-]

I'm an Industrial mechanic. This was pretty simple, but when folks just aren't mechanical, this thing was a frustrating nightmare. the seller kicks himself but is glad you got it working I'm sure. The other freak zone is when a new land owners waterwell stops working. Many times it is a simple fault, but it is always, OMG My Pump motor is dead! Not always....

[NotThePulla]

Its always cool to see the rolling shutter effect from the camera on high speed moving vibrations. At 1:03:20 it looks like all the parts on the generator are moving and wiggling independently.
Great video, always fun to watch, and youve inspired me to start my own Red Mango Rebuilds channel since I do alot of small engine rebuilds already, might as well have some fun making youtube videos along with the rush I get from getting a non-running motor to fire up! Thanks again and keep it up man

[Zainkhangaming]

I like the way you fix and repair generators, and your knowledge about these things is phenomenal.

[zrkn]

Predator gennys are notorious for clogging their spark arrestors, sweet find on this generator. Congrats!

[YukonHawk]

video as always. Whoever worked on that genny prior to you had not one clue as to what they were doing. Nice job to get it up and running again. A lot to be said for those older genies still kicking around.

[patorilim]

I use to use those generators on job sites and their pretty tough! Glad you restored it! If properly maintained, they should last a very long time!

[tubemember]

Great video as always. Learned that those spark arrestors can and do fail. Also learned that nifty trick with the air compressor and the handle grip.

Nicely done. Merry Christmas!

Hello James:

I love your videos. I entertain myself and learn a lot watching them.
As I told you in another comment, I maintain two generators that my brothers-in-law own and I have been able to apply techniques and knowledge that I have learned from you all these years.

Thank you for your dedication to filming, editing and uploading them to YouTube.
