Propane Generator Will Not Start - Feels Like Low Compression
ฝัง
- เผยแพร่เมื่อ 17 ส.ค. 2022
- A local subscriber contacted me about this AllPower propane generator. Currently the engine will not start and it doesn't feel like there is much compression. Hopefully the engine is not junk. Let dig in and find out why this 13hp Jingdong Honda clone engine lost compression and with any luck fix it.
Generator Model: APG3650CN
I use Harbor Freight Super Heavy Duty Degreaser in my ultrasonic cleaner.

Purchased this th-cam.com/users/postUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y after researching several brands.Reasons for picking this one was, dual fuel, I don't have to carry gasoline and stink up my truck bed!Propane is so much cleaner.Quiet 62 db, won't piss off neighboring campers!Less than 100 lbs, can lift in to truck bed.I can run my 30 foot Transcend 261BH, AC among other appliances.
I was watching this video and I noticed when you opened the valve on the propane tank you opened it all the way then turned it back clockwise a little and that can be a huge mistake, those valves are a double seated valve and if not opened tight can leak around the stem when a valve gets worn. I spent 20 years in the propane business dealing with millions of gallons every year so I know most everything that can go wrong of course not everything so I try when possible to help people divert dangerous situations. I enjoyed the video, God Bless and stay safe
Good to know. Someone told me once you never want to open it all the way. Never questioned that advice.
I'm not real sure about your comment. Is it okay to turn a propane tank valve one turn on without causing damage?
@@tomtee4442 If valve is perfect that might be ok but they are double seated and designed to either be closed tight or open tight so if your not opening it tight you should check for leaks which is actually recommended but in my 20 years in the propane business working with many thousands of valves probably less than 100 leaked when open tight so I guess if you would rather take a chance rather than take the time and effort to open them all the way that’s up to everyone. Good Luck and God Bless!
I wondered about this year's ago my aunt gave me a 30 pound aluminum propane tank my uncle had taken it off his camper because it leaked around the stem it was full so I wanted to use the fuel in it and I found it didn't leak when opened up all the way way tightly open now I know why
Agreed. Full open or full closed!
6:23 "This should be an easy fix..." Me, looking at the video length - Wow, our man James has eternal optimism, doesn't he? 😁😆😅🤣
👋 y'all just know that having discipline, attention to details and patience will go along way ... James you're a good example of that🙋🏾♂️
Did you notice James the the engine only fired up as you released the ignition switch, which made me believe that the switch itself might be faulty? Look at that little portion of the video to see what I mean! 👏👏
James - your videos are very therapeutic for us shade tree hacks. Your methodical approach is easy to follow and helps us wannabes at least attempt some of our own self repairs.
Considering only the push rod guide needed to be replaced, this simple fix fought you all the way to get this running consistently. The Predator guide design is much better than the original.
Glad to see another machine saved from the scrapyard. Well done.
I guess the Rato engines are a bit closer to Honda engines than the Jiangdong ones. The 302CC Predator is a Loncin V-valve engine which was designed with input from Cummins Power Generation and which is among the best Chinese engines. It probably also helps that Loncin is a motorcycle builder and has done work for BMW.
I would buy a used generator from you anytime.
An outstanding repair as usual. 👍
ditto
So would I.....if I lived in new England......alas, I reside in old Blight, 3000 miles away. 😢
Nice video. Always look forward to see what you are working on. You are certainly keeping busy!👍👍👍
Enjoyed this video professor , watching you trouble shoot is almost therapeutic :)
Just a suggestion. I use a piece of plate glass to check if push rods are true. I also use it with 1000 grit sand paper to face heads if I remove one.
Great video as usual James. I am learning a lot .Keep up the great work.
The melted pieces that you found in the head might be from the push rod guide , some of them have plastic on the inside of the hole for the push rod . This probably means this engine got hot at one point . Great video as usual .
That is a good point. I had meant to mention that the style guide I pulled out usually has plastic around the cut outs.
Makes sense to me, leaves in blower housing, valve cover gasket stuck to head, push rod guides melted, all adds up to a severe case of overheating.
i was about to say same thing . believe around the square holes they had plastic inserts on some engines
He does great videos , really coulda been a shop teacher
That is exactly what it was! 👍
Such a detailed step by step video to learn a lot from this informative video. Well done… great job
Another great video James thanks for sharing your knowledge 🦘👍
I have learned so much from watching you and am now able to recognize so many issues before you mention what it is. Thanks so much!
Very nice to see the engine runs after the valves were fixed and jt makes power i like these episodes dont see propane generators much @James Condon
Learned so much in this troubleshooting process.
I've been enjoying your videos. You really know your way around this equipment, and you are quite good at narrating yourself . Keep up the great content.
Thanks James. Your videos are brilliant and a fantastic source to help us better understand our own generators 😃
Wow a propane unit. Nice find! That video was awesome. Thanks.
So good to see a genuine very nice guy educating so many people in this way well done again my friend great work as always
Another great video ...I've learned more from James class than I did in high school auto.
excellent video!, it surprised me that it can almost handle 6000W with propane, usually propane the most power you can get is 5000 if you are lucky, at least with the pressure that is used here.
btw the other day a friend of mine call me, it's genny wasn't working right, i said: bring it over i talke a look, i fix it in 30 minutes like a pro, 2 years ago i had no idea how to adjust valves, deal with timming issues, clean carbureators, now i can do it, i still cannot believe it!, i learn everything in your videos!, thank you!.
Loved the investigation and resolution of the coil/spark problem.
Doc., another successful operation. This patient had several problems.
I'm not even a quarter of the way through and I like this. I had better not enjoy it too much since it's just a video, but the way you are presenting your work through the problems is really encouraging me to try this myself- and stick to it! Thank you for sharing your work!
Great save!🤘🤘 It's nice to have a different challenge to keep the videos fresh!😎😎
Nice clean up and troubleshooting James😊
Great job! Nice to it comes back in use.
I have watched so many of your videos that 8 of 10 times I can tell when an engine is running fast. Another great fix. 👍
Another very much informative video James thank you. Who would of thought a .30 gap would work? Thanks James great video. Ed
Impeccable diagnostics. Thanks for bringing us along. A project is rarely completed without a little touch-up painting.
I'm still not happy with the starting issue. It still doesn't start easy enough for my liking. That said, you definitely know your stuff, and are an excellent mechanic. I really enjoy watching you work, and am learning a lot from you. Keep up the good work.
Thank-you! What a great way for me to spend an evening!
Thanks for the new video. Because it ran once, it was confusing that it wouldn't start. This was a good example of troubleshooting.
Wow that non starting generator sure had me stumped. I figured it was a coil that was malfunctioning. But you figured it out and it sounds good for now. Great job once again. Thanks for all the videos.
I like these videos better than the product reviews.
I'm here for the diagnose process and fixing of small engines, I don't need a new generator (I live in western europe where the power never goes out)
Excellent troubleshooting. Awesome. Thanks for sharing
Excellent video - the content and isnructions with all the required detail are the kind of quality someone requires to actually troubleshoot and ultimately fix something like this. I like that you had failure through the video but were able to troubleshoot further and actually get to additional issues. Some of the check list items were unsuccessful and others were very key to resolution. thats how leaning works. you tell that you did this video to help people not highlite your knowledge which is impressive details you share. quality video. I will subcribe as this is the level of instruction and detail one needs to be able to work through an issue like you just did. thank you
good job, just goes to show you what persistance and profesionlism your the best!
Semi flat black looks good as well. Also i liked how the handles were hidden.
It is a Great job.That you testing-the
problem stap by stap with-a knowledg.
You sir have an amazing amount of patience, also your skill to fix things is Absolutely awesome. I have learned so much from you because of your clear way of diagnosing issues. I want to thank you for that James. Keep up the awesome work and God bless you good Sir.
Thanks, I always enjoy watching your repairs. I wonder if ever considered including a decibel reading to let people know how loud each generator is. Thank you James for enjoyable and informative podcasts .
Hi James.
You're one cool dude. Never gets flustered, never loses your cool, never give up......
I consider myself a calm guy, but there have been instances when I could see myself kicking a generator you were working on. And your attention to detail is commendable.
I would buy one of your generators sight unseen in a heartbeat!!
this kinda inspires me to try and locate a generator that has some issues to tyr and get going on my spare time and to have one ready incase of a power failure
Hi James thank you for all the work you Put in for us ,, I am a Newbie to your channel from Northern Ireland . Just on the point of propane powered engines .I. Used to run my cars on propane ,it is my experience they are harder to start.
That was a good one to keep you on your toes. but you fix it and it looks great, and run's great as well.
One thing I like about your videos is, that you show the diagnosis’. Other just figure it out an do the job. This is much more interesting because I am diagnosing as you go.
Hi James, I am a recent subscriber, and I continue to enjoy your videos thoroughly! I know that you comment from time to time on matters of shop safety such as keeping CO levels down. I was interested to know what type of gloves you use. I know that my hands get scraped up etc. There are some chemical hazards too I need to avoid with work like this. I would enjoy more on your shop setup and the type of tools you use and general shop safety. Keep going! You are the first to capture my wife's interest on repair matters. Sometimes I ask her if she remembers something from your videos and she does! She and I both admire your calm methodical approach. Best to you and your family.
One man’s trash is another man’s treasure. Nice job on the filming!
I will never understand why China would go thru all the trouble to clone a machine, and then cheap out on a 5 dollar part?
Essentially, ruining their reputation. Thanks for showing us this video.
As the saying goes.....crap parts make for crappy machines.
All of the parts are cheaper and lower quality than those from a more expensive well built machine. James has compared a present day Chinese clone engine to engines built 30 years ago and the difference is striking. Chinese clones do not really have a reputation to save.
Buy cheap, buy twice
Great video, thank you for sharing it with us, very helpful.
I have been running a 10K All Power and had hard start issues. I will have to check the coil gap. Had problems with gas regulator freezing up in moist conditions until there is enough engine heat. Thanks for posting.
Nice job James. Thats funny. I thought the green and black pull start looked better than all green myself. It's all just psychological but cleaning it up adds almost as much value to the generator as fixing it.
Thanks to your videos I've learned how to do valves and everything else I got a 300.00 used 800 hrs on it wen 3800 inverter generator running better than ever I'll be making a video on it's status soon enough
Excellent video: I have also seen a check valve in the propane tank not letting enough fuel supply to the engine. Took me a long time to figure out what was going on with it. Thanks for another great video.
Re: check valve.. my propane guy showed me how to unstick that valve. Just pick up the tank about 6 inches and drop it on concrete or a sound rock. I got a fill up, took it home and the tank wouldnt work. I went back to the propane station and the nice man showed me the problem
Never had an LPG engine so your comment about a smaller gap was definitely beneficial to me.
Smaller spark plug gap. Had never heard that before. While a lot of your videos, are often nothing new though some are they are all sound practical advice and re-enforcing on troubleshooting small engines, pretty much all gas engines large and small I find them all very good especially the generator problems. But you can’t make electricity from a gas engine if it doesn’t run. Are carbs and/or the LPG regulator to carb input on LPG engines subject to any problems
Great job once again James!!
Thanks Gary
It's crazy how often engine related issues don't require new parts but just adjusting or cleaning. More often than not compression related issues seem to be valves need cleaning and adjusting due to not seating properly or in this case the push rod guide completely worn out. Great preventative maintenance, like you said it could've resulted in the destruction of the engine if that guide got any worse
Very nice I have learned so much from your videos. With those panels you painted black it may be time to try you hand at pinstripes 😬😁
Hi James I always enjoy sitting in your class mate I have no experience on working on gas generators but nice to see you dealing with the problems so efficiently Thank you for sharing James
Thanks Dean. I bet you could fix one now after watching all my videos.
@@jcondon1 Hi James watching you work does get addictive I find myself talking to the screen trying to find the problem as you are working Sometimes I get it right too I enjoy your classes as you are a good teacher
Loved this! I work in propane combustion. Great diagnosis. Suggestion tho- anytime you turn off a propane generator, close the propane tank to get all the propane out of the line. Sometimes a backfire will occur if not. Love watching your videos!!
Hi from Portland Oregon
Great video and alot of useful tips. The black paint job came out good. But watching for over a hour I wished you painted the parts lime green or orange along with some simple pinstrips or decals!
Very recent subscriber here. Content is first rate, and your attention to detail is well ahead of what anyone in the consumer side of things will expect. Going through your new as well as older videos. Learning a significant number of things. I am American, but retired and living the last 4 years in my new home in the Philippines. Power outages are common here at least weekly, sometimes multiple times per day when things are bad weather wise. I bought and installed an 8000W generator diesel powered, even before the roof was fully on and we had not even closed up all the windows... I have had maintenance on mine, and your content, as you say on every video, "I hope this helps someone out" is not in vain or lost on me here.
I now feel much more confident with my own system. MANY things I have learned, too many to mention here. But MANY thanks, as I am quite weak on the electrical side of this machine...
Good to hear. Thanks for the feedback.
Nice paint job. Down south that would be called a Craigs List tune up. The flat black top covers are a definite improvement over the pea green original color. Nice job. I enjoy your channel.
Super video and a great help. Thanks again Best
At least it was an easy fix with this one, just a bad push rod guide, nice work James!
Ah... right at the end you said you weren't sure how the coil/flywheel gap got out of whack. I was going to ask you how it was running earlier with that huge gap in place. I'll read through the comments to see if anyone else has an idea of how that happened. Great video, thanks for sharing!
Currently parked under a huge shade tree got my wen 3800 generator going and ac going watching this here in the van in Chantilly VA I love being out of my apartment
Awesome video, I’ve learned a lot, thank you. Job well done.
Excellent video. One suggestion tho. Clean the rust off the flywheel magnet before setting the gap. With the gap that wide before, the rust would act as shim when making the adjustment.
Totally agree about cleaning the rust off the flywheel. I had a Moped many years ago that had not been used for a while when I got it the spark was poor. I cleaned the laminations up on the transformer and flywheel and that sorted it. You obviously know what you are doing on these machines and it's great that everyone rips off the Honda engine. That makes it easy to carry spare parts. Obviously probably not good for Honda unless they get a kick back.
Amen
Hi James I watch you alot I saw a mouse jump out of that generator at 27.19 minutes pretty funny, he must have been in there while you were working on it. Thank You for your videos!
Saw the same! Wasn't sure if anyone else saw it too. lol
Great content as usual and it's crazy that thing ran at all as massive as that coil gap was. Odd it was so intermittent. Was hoping for some fresh Kawasaki green on those panels, but can't go wrong with flat black. Someone will surely be glad to have it and not have to mess with gasoline when using it too. 👍👍
In this case I think green would have been better. Not too late to change it.
Excellent Job, Thanks for sharing James
Thanks Brian!
Great work as usual!
I have this same generator. I purchased it in 2011 just after the Northeast experienced a snow storm around Halloween. We were without power for more than a week with that one. In late September 2020 it failed in the middle of another power outage (just under 2 days). It is the reason I subscribe to this channel. The cause for the failure was the coil. I had just 23 hours on the clock when it happened. Thanks for all the troubleshooting help.
Interesting. That for the info.
Good video James. I would have probably work around the decals when it came times to paint the rusted area. I would have placed some painting tape in a curve way to match the design, after removing the rust, and painted that area white to merge with the green/white decals. The decals makes the generator look good. It would have take less paint too, but it just me. At the end you did a great jod fixing it. Thanks for the continuous training you provide. It is much appreciated.
Not just you. I was very disappointed in the resultant black finish.
Love this video. You might want to try a rust converter on some of those spots in the future. It turns the rust into a black surface that can be painted. Really look forward to your videos James. Nice job.
Rust converter is very good for smaller patches.
My sister in law taught me this a couple of days ago. It works
I just want to give a shoutout to a guy who loves generators, and who also knows to make very engaging, interesting and educational 1h+ long videos.
I love generators because they're so underappreciated; they're not flashy. they're not a status symbol. they're that quiet unassuming machine that got your back when needed. that's what I love about them.
Another great video. With Propane or Natural Gas engines with spark issues, I always replace the spark plug. I noticed in the video when you jumpered the electrode to ground, the spark was coming from the porcelain insulator.
Great eye! I missed that and had to go back and check.
Bloody hell James, you must be healthy pulling that bloody starter like that 🥵
Great video! The best from Oslo Norway!
That was interesting, a pretty simple fix. I had a Murry mower that seemed like it was very low on power, I adjusted the valves, it made a big difference in power, felt like it never ran that good, about 30 minutes later it started smoking really bad. Then I
noticed it was blowing oil all over.
Took the engine apart, the top compression ring was broke in 2 places. And the piston was sloppy in the cylinder.
Thanks James.
So beautiful, in that mat gray 👍
Always educational, I liked the green better,
Me too
Lot of information here! Thanks!
Congratulations good video as always.
Great video Jim. I've seen the rod guides fail on LiFan engines before, even as brand new. Oddball items like random coil failures, recoil failure and inaccurate tolerance / low quality material issues often affect these Chinese made clone engines, especially if they are neglected. No issue if purchasing used at a very inexpensive price, but I wouldn’t recommend buying anything new that’s equipped with one of these and expect it to be long term reliable.
Indeed. Which is why I go with Honda on anything which matters.
@@jamesws3
I seen where Honda is having some engines made in China.
Everyone’s having things made in China these days. I’ve had a predator generator for several years that has served me well and is still going strong. Some things made in China can be well made. Just depends on the cost it’s being built to per manufacturer demand.
I have seen that before, Thankfully the plates are widely available.
Nice job James
The plastic you dug out of the head is the nylon around the holes in the pushrod guide. Merry Christmas Jim!
I agree. Usually that type of valve guide plate has nylon around the holes. Thought is was strange that this one did not. Did not even recognize it as plastic at the time.
Considering it's a propane only generator, it has the power to hold its own. I was very surprised it held at 6000 watts, though I would never load it that high for long just as you mentioned. Nice pic up and resale item. I wonder how dirty the wave would be on that one.
Thanks for the vid James.
It's cool that you are able to start with what is essentially a basket case, and not end up throwing wrenches in a fury. I hath not the patience for that sometimes.
Gotta love the 'ole used car salesman Tremclad job haha. You really need a sandblasting cabinet James.
I do the same thing to ATVs all day. One of my most important tools is a zinc and nickel plating rig. Fresh factory hardware really makes a big impression.
Need more tools and more space
When you noticed the oil leak at the valve cover and began loosening the hold down bolt the bottom of the gasket pulled back into the cover. Definitely was not seated on the head correct. Also I agree with others that what you pulled out was melted plastic from the pushrod guide plate. Awesome job as usual. 👍👍👍
That did not occur to me at the time. Definitely was the melted plastic.
Great job as usual. Keep it up.
I have a Allpower generator That we ran for 4 straight days in an outage , ran great but not the fuel economy of a Honda or Yamaha .. Good fix James ! ENJOYED
Thanks Shawn
