  James, I had a Coleman generator like this and it ran the same way from new. It ran fine under load but stumbled occasionally when not under load. I never got it figured-out. I appreciate your efforts and don't mind the length of this project, this is the second time I've watched it and have learned more this time around! Keep up the good work.

  Seriously I love that you don't make your videos short! Please never change that. It's one of my many favorite things about your channel, the other thing I love about your channel is how much depth and attention to details you put in and you're extremely skilled at working on small engines. Your content is pure gold. Thank you for your time and pubic service to your viewers don't ever change how you make your videos ☺️

  You're not alone. I "had" an 8 hp techumsa with exactly the same issue. It was on my log splitter I owned for 20 years. Because it would "run" crummy I just let-err-rip spit & sputter while I split wood. Every year or two I'd try fixing it. I did everything you did 10-times over 20 years. My carb was NLA & the closest carb I could get was for a generator. That didn't fit or work well at all. I bought every carb part available for my engine. What I ended up doing that fixed the hard starting & running ruff was....the little brass screw in jet on the top side of the carb ..... I used a finger drill & made the through hole (not the tiny side hole) larger one drill size at a time. That finally fixed it - Yahoo & sold the log splitter. I ever see another 8 hp techumsa I'm not fixing it - whatever it takes to replace it would be a shortcut.  Grrrrrr8 video 👍

  I was a mechanic for years and eventually owned a small engine shop when this engine was new.  My shop was a master service dealership. I have 2 comments. First these flat head Tecumseh  engines never were known to be smooth runner's. . 2nd your not considering a sticky governor. Start with checking the  governor rods. For abnormal bends , and spring condition,  some models in the series also had a secondary  spring. To help stableize movement of the governor rod.  It seems you covered all the other likely conditions well.

  Another great video James ,2 tricks I &nbsp;use. Valve lapping suction cups are prone to not sticking very well, I now use a 3/4&quot; dowel and stick it on with hot melt glue , works great. The other trick is when grinding the valve stem use a vernier caliper &nbsp;to measure valve length before grinding.<br>Saves putting valve in and out of the block to measure the clearance.<br>You get top marks for persistance.

  That was absolutely worth <a href="https://www.youtube.com/watch?v=H4fTY8ve09s&amp;t=135">2:15</a> of my time. I have a similar unit that has been under the bench taunting me. After the comprehensive video you put together, even though the machine is not 100%, I gained enough knowledge to give mine another shot. I appreciate that you took the time to show almost everything. You presented fuel, spark, timing and compression and gave each one it’s due. No one can do that in 59 minutes. Your length of video meant you could show all the complexity, and you share your process and you thinking. That is where your content has more value than most. Thank you for this video. It gives me confidence that I can try to take on a similar challenge. You have helped me a lot in the past and you continue to do so here. 6 Stars, on the 5 Star scale.

  That&apos;s a lot off turd-polishing for very little return! &nbsp;The best part about things that are hard to troubleshoot, is when you do finally figure it out and get it going.

  I know it&apos;s not the same application, but when I used to maintain a fleet of pushmowers and other motorized small engine equipment, Tecumseh always proved to be problematic for weird things like this. &nbsp; They were always the more tempermental units to get running and even then, they would never act really <b>right</b> when compared to B&amp;S, Champion, and other small engines of the same form factor. &nbsp; I&apos;ll be watching to find out what you find out in your investigation, but that&apos;s definitely a head scratcher. &nbsp;From what I can tell,. you&apos;ve gone above and beyond, this thing should be running like a top by now.

  I really enjoy your videos, man! I’m a novice at small engine repair and so watching your content feels like I’m being familiarized with the basics and offers me a wide amount of foundational information to then use when I’m tinkering on my own projects.
