I managed to pickup this Generac GP7500e generator for free. The previous owner said it was running fine and then just stopped. He cleaned the carb, bought a new battery, replaced the spark plug and brought it to a shop for repair. Based on the estimated cost he just purchase a new one and was basically throwing this out. Can it be fixed?

Generator Model# 0059432

    We have used the youtube.com/post/UgkxOTeIs0vv4_9B5hsmnLsk9r930uDQL… for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!
  • I know its been 3 years sense you made this video I just want to say thank you for taking the time in making this video. I have a generator that's no spark no compression been studying up what might be required to get it up and running. I can tell your very patience I hope your still doing and sharing your repair work.
  • You’re quite there surgeon! I’ve never watched an entire surgery on a generator, although I’ve participated in many surgeries. I wish I had you nearby, as I’ve got a Generac that developed an undiagnosed problem, plus now it’s seized. One thing in humans, you can deliver meds to counteract the problem....not so in a generator (except carburetor cleaner). I’m in a County where it’s actually not safe to trust anyone claiming they are a mechanic it have fixed the problem before. Often you end up on the losing end of the stick...First is usually the theft of your parts, second they couldn’t find the problem but you owe them for time and labor, or there is no such business ...and they said they pick up and deliver. If there is a criminal venture, it’s going on in Northern California small counties!

    Jim, Your videos have inspired me. Yesterday I picked up a Honeywell 5500 generator (very similar to the Generac line). It was advertised as non-running, needing a new carburetor, and making a ticking noise. I picked it up for $70 and just happened to have a correct donor carburetor for parts. Following your lead I was able to get it running well and producing power. Thank you for sharing your significant knowledge and experience. Cheers.

    Years ago I gave away a generator thought it was no good if only I could’ve seen these videos years ago.Thanks so much for posting such great clear and concise videos.

    I purchased a "non-running" Generac XP8000E with only 13 hours from new. James, thanks to this video I went directly to the cause. Got it on the heel of the cam and used a soft hammer and a long screwdriver and BINGO! Changed it onto 5/30 Synthetic oil and it runs like a charm. You are truly appreciated Sir! Thank you!

    Hi James. Thank you very much for the information you gave me. I found the model number, look it up and ordered the exact same gasket. Thank you again, for all that you are doing.
  • @MrJav69
    Get this case closed up no pun intended great score my friend!!!
  • @alanstant9356
    I have catching up on your videos and came across this one. That was an awesome trick with the water on that rotor. Never seen that done before but you pulled it off. Amazing job my friend.

    Great Video. I Have an old Generac 12 Kw stand by generator. Motor will turn over but won't start. Turns out number 2 cylinder has a broken intake push rod. Took the head off and it too has a stuck tappet. In the up position. Just touched it with a hammer, dropped right in. I'll let it soak in some upper combustion cleaner. It's an old unit but came from an estate with regular maintenance. Oil is perfect. I saw your video a while ago and had to go back and watch again. You are more ambitious than I. Don't really want to take this whole thing apart. It's almost 20 years old. Just get it running.

    Since watching James , I would not be involved with GENERAC prt 17 is just on the exhaust awesome ⚡️ video
  • @67plymouth440
    Thank You for making this video. I can only aspire to your level of mechanical expertise.
  • As a family looking for a whole home generator, we watch these videos of all these brands being repaired and it makes our decision easier. Honda!
  • @markfabre7682
    Wow! I learned something new. Based on what you went through for the rotor/stator tear-down, when I run across a stuck tappet, I am going to soak it in penetrating oil and see if it frees up before ripping everything apart. Hindsight is 2020 but foresight is 2022!
  • Great job again James! and the water trick was awsum! Never seen this one before..love the vids. always informative!
  • I’m having problems getting my Generac generator to start. It has a clean carb, good fuel, spark, and with starter fluid. A guy in another video had similar issues and found his intake pushrod just laying unconnected. I was hoping this was my problem after pulling my hair out. It wasn’t. I sure hope it’s not the same problem you had because, although an excellent tutorial, I got anxiety watching all the bolts and nuts you took off. I wouldn’t be able to keep track without a labeled baggy for each one, lol. I’ve already lost the two nuts that mount the carburetor, lol! Excellent job! Instant subscriber!
  • Another winner , the water was a winner ! I saw one fellow that used bread , worked great . Great video
  • @johnwahlers3363
    That was some real MacGyver stuff you pulled with the water to break the stator free. Very impressed. Great video.
