Small Engine Repair Honda Won't Start?
Вставка

- Another thing to check that I did not mention in the video is some engines like this one has a low oil sensor and if the oil level is not high enough the engine will die and not start.
It doesn't matter if you have a Harbor Freight predator engine, a nice Honda, Tecumseh, or Briggs motor they are all set up the same with similar components. This videos shows some of the main causes for your engine not starting. Since its getting cold you'll want your snow blower or generator to start right up. Since this is a small engine it will work for your go kart, tiller, pump, generator, snow blower, mower, edger or whatever you have in your garage.
Here are some simple tips to check and if those don't work it might be the carburetor.
1. Check gas
2. Check on/off switch
3. Check spark
4. Check oil level
5. Check carb.
I've been working on small engines for about 20 years and almost every time an engine has been sitting over winter the carburetor is gummed up and needs to be cleaned.
Hope this video helps someone out. Good Luck!

Thank you! Just cleaned out my carb on Honda 160 engine. Did exactly what you showed in the video and she started right up. You saved me at least 200 bucks!!
Glad it helped
Thats amazing!
I just recieved a plate compactor with a gx160 honda engine. Got it on the cheap because they couldn't start it. Im going to give this a try for sure. Fingers crossed.
You would've paid two hundred to get your small engine started?? Is that an average small engine shop bill?? If so... I'm changing shops lol
The choke(white) lever can be removed & the round pin on it placed in the end of fuel line. Instead of crimping the fuel line
There is another needle jet above the small jet you screwed off, it sometimes falks out or you tap the sides and it comes out
Good point!
I learned two things on my last Briggs carb clean and diagnosis:
When i removed spark plug and pushed possible air/fuel out of cylinder, i cleaned lightly with my starting fluid. When i tested for spark... it lit my light spray off fluid. Hard for my eyes to look for spark... but easy to see a 2 second fire! (I will actually purposely use this method in the future!).
Secondly, my single bottom bolt to the carb bowl supplies the main jet! I used my torch tip cleaner kit, dupray, and comoresser air... she fitted right up! Fresh gas, a bit of mystery oil... and my freebee pressure washer is on its way for use!
Right on!
Thanks a a million 'I done most of this 'it was full of gunk 'but I didn't clean that little brass valve 'I will do now
Thanks again ❤
Yay I finally got me engine fix for my go kart it was the choke it was dirty so I had to clean it!!
UPDATE:1 year and still cranks within the first 2-3 pulls. Probably will buy another when this one finally does bite the dust ua-cam.com/users/postUgkx43QMbQqu67IZadu9ou8Sg1BdrunMRNqX . No issues at all. Very happy with it.UPDATE: After 6 months of use and over 70 uses I would still highly recommend this pressure washer. It does vibrate a decent amount but never had it “walk” like others have mentioned. No oil leaks, still seems to run like the day I bought it. Still cranks within 2-3 pulls every time. Very happy with my purchase!Have used it about a dozen times now. Plenty of power, cranks up on 1-2 pulls every time. My only complaint would be I wish it was a little taller to make it easier to walk with it (hits my ankles a lot) and that the two hose connections were a little further apart but it hasn’t caused me any issues. Seems to run a good 1-1/2-2 hrs on a full tank, overall a well built machine and definitely worth the money in my opinion.
The Hondas will last forever.
Thank you 😊 my engine is now going after watching this video the tiny hole in the jet in the carb was blocked very hard to see but I used a bristle from a wire brush to poke clean the engine started straight away also did not have to take apart as much just take 2 bolts of at the cup then use small flat head to unscrew the brass jet used a wire brush bristle to clean it engine going in 10 minutes 😀 👍
Thank you very, much, your Video has helped me a lot, just checked with the spark plug, it's on! Be Blessed hundred times
Right on!
I have a greyhound 6.5 it’s similar to those engines. All it needed was a pitcock for the gas tank. Started up and ran beautifully when we poured gas in the carb without the gas tank. Now we got the gas talk on and tried starting it even after we poured a lil gas in the carb it didn’t want to start at all
That's a weird one, did you end up finding out the issue.
@@-DIYPRO- yes, apparently the throttle was attached straight to the governor ( it’s on a go kart now) so there was no idle setting, the throttle was fully closed. I ended up having to get someone hold the throttle a quarter of the way open while I start it to get it to fire up.
Couldn't tell from this video, does the plug need to be grounded against metal chassis to spark ? What do we do if there is no spark ?
Yes, I usually just rest on or next to the engine block.
@@-DIYPRO- I finally figured out why my hole auger wouldn't start: I did not get the torque bar with it and that closes a kill switch near the engine when installed. Took me a day of research. These things are really dangerous and I emphatically suggest no one get one if they think it's a one man tool. It takes 2 big guys to use. i realize that's a little off topic as this vid is for motor only. Carry on.
Great video i threw some gas in the hole and yanked a couple times and fired up , gonna clean the carburetor Tomorrow
Let us know how it goes.
Me gusta esta video mucho gracias par todo information! need pero olvidaste mencionar que revisaras el tanque de gasolina en busca de residues y filtro de gasolina GRACIAS
thank you for your video but i have a honda 160 air compressor stopped working i changed the carburetor, spark plug, And it does not turn on, could you tell me that it continues to check
10:33: Looks like you got a little helper there.
Yes. Problem is he can't ever remember where he put my tools!
Thank you for this very helpful video... I had the same carburettor problem and it's solved now.
Awesome, glad it helped.
And what about the air/fuel mixture jet ?? Located under the plastic idle screw, if this is blocked then no starty or at the worst it won’t run clean !!
Good catch.
Im getting a gx270 or gx390 and ima do plugs, oil, dirtbike carb and chuck it on a go kart
What if the carb is brand new and it’s still somehow not getting fuel to the engine?
You sound like the Project Farm guy.
PF has an awesome channel so I'll take it!
Thanks so much for this beautifully explained and informative video...
Glad it was helpful!
My Honda generater , don't have power when I put Airfilter it need me to keep out Airfilter to have power,I cleaned the cuburater already
@@-DIYPRO- I need help sir my Honda generater need me to keep out Airfilter to have power,if I bring Airfilter back it's don't have power,I already cleaned the cuburater
My carb got gummed up. Mine, an older 6.5, carb gaskets were definitely not ethanol friendly. The gaskets swoll and broke down clogging the jets.when I took of the bowl there was a goo of melted black gasket and gas slime.
I had been running it every day for about a month. Took a weeks vacation. Didn’t drain the bowl. Came back and It wouldn’t start.
Been there!
So what if you have a honda 5.5 with less than an hournon it valves lashed properly has plenty of spark plenty of fuel going into cylinder and plenty of air and will not fire at all pops and that's it thank-you!
If the lash is correct and you are getting spark then it's probably the timing.
Very helpfull video. What kind and size of screwdriver did you use to unscrew the nozzle?
Small! Not sure what size it is, doesn't have any markings on it.
Other than cleaning your carburetor and you’re still not getting fluid how do know , when to just swap out carburetor with new one?
If you test it out with some starting fluid and it starts up then dies then you know for sure its the carb and you can replace it. If you shoot carb fluid into the carb and it still doesn't start then it's something else. Check spark plug, check oil level (some small engines have oil level sensors that cut the engine out if low oil)
I had a spring on my GX 390 underneath the gas tank that broke. Wouldn’t crank for anything. To the shop it went.
On another one I have I bought a 14 dollar carburetor and it ran perfecto.
Was it the thin spring
junior cook I’m not sure. It was under warranty so I let Northern Tool fix it.
Does the bowl have to be full (float working) in order to start?
No, you can start it with just a little starting fluid in the carb. To keep running, yes the bowl needs to be full.
I have the same engine I can't understand why it doesn't start, it has compression, it sparkles, I cleaned the carburetor but nothing, even putting gasoline directly into the cylinder it doesn't start, what could it be?
Mine is currently covered in snow or else I'd go double check but I'm pretty sure these have a low oil sensor. That would be my next check. Double check that it has oil and that it's level. I say that because I had a tiller once that tilted the engine slightly and so even though it was full on the one end it was actually low on the senor side and would always shut off.
Thanks bud, nice one. I had to rewatch it lol i remember watching it long time ago. Cheers was great help
HMMmmm - Didn't you think that the sediment bowl on the carb needed to be looked at?
That wasn't the carb from that engine. For sure if there is sediment in the bowl then it needs to be cleaned out.
What if it doesn’t run after spraying carb cleaner in the carb? My 240x on my trash pump won’t run. I sprayed carb cleaner and nothing. It has spark. But won’t run. I put fresh gas in it, new plug, and sprayed carb cleaner down in carb. Still won’t run.
Hi there great video. Can you please tell me what oil you recommend for these engines? Thanks.
I use whatever i am putting in my car that month.
Thanks mate, you just fixed my generator.
No problem 👍
I change my carburetor and coil for my water pump. It will crank and show signs of starting but will not start. Should I check the valve clearance and compression
Do you have spark?
This video allowed my gx390 to once again crank up and run. It turned out to be the ignition coil. Quick question - I bought my pressure washer (4k/4gpm - gx390 this engine) and after 2-3 pulls it will crank but it takes a little muscle to pull. The pressure washer pump is removed and I made sure the engine is not vapor locked by changing the oil and also removing spark plug (pulled a few times to rotate it).
What would cause the pull to be pretty hard? I know this is a bigger engine but what could it be?
Need to adjust the values
@@srdjannakalamic5856 While you're doing that check the exhaust valve rocker arm for cracks. Usually the 160 and 190 engines are the bad ones but while into the valves it only takes a second to check.
Hi there! For winter storage should the choke be left on the on or off position?
Choke doesn't matter. Important part is to either run the carb bowl dry or if you have a fuel cut off switch then turn it off so no fuel goes into the bowl and run it til it shuts off. the killer is ethanol fuel sitting in the bottom of the bowl. It will separate and gum up the ports.
Or if u dont wanna do all that carburetor stuff u can just buy a new one for like 20-30 dollars on ebay
Done that a couple times.
It's a way more satisfying to repair stuff. You lurn and you recycle. Good for you and the nature.
❤❤
Great video. Thank you for sharing your knowledge.
Anytime!
What do you think would be the problem if it’s leaking a lot of oil
I guess it depends on where it's leaking from, the case, from a seal, out of the carburetor?
@@-DIYPRO- I opened it up and the carburetor was covered in oil and were the air filter sits was also covered in oil. Then my brother found out that a rocker arm was broken in it

I hope I can get a response on this question.
I have a 2008 Honda clone 6.5 horizontal shaft. It was in the original box till just recently when I aquired it. I filled with oil and gas and wouldn’t start. I checked the compression and it’s 28 psi. Checked the rockers and they’re moving like they should. I removed the rockers and physically moved the valves up and down, both seem to be seating properly. Filled cylinder with oil and tried again, still 28 psi. What’s my next move, remove the head and check the valves?
If your engine is hard to pull, then your compression release on your camshaft is broken
That repair will take a little more time!
Does WD-40 work for cleaner?
No. Brake cleaner and carb cleaner are fast drying solvents. WD won't dry up and will actually start collecting dirt and clog it even more.
I followed the instruction , my Honda pressure washer started right away )))
Awesome!
Thanks so much very helpful video excellent explanation
Awesome
Glad it was helpful!
how would you go about inspecting a honda gx390 before purchasing it off craigslist
Does it run? If not then low ball the price until you feel comfortable knowing you might have to put a lot of work into it. If it runs then how does it sound? Check the oil, if tar then you know they haven't done anything to it maintenance wise. If clean then you know they tried to take care of it.
@@-DIYPRO- I found a gx390 listed for 400$ if it doesn’t run well how much $ could it cost getting it to work
Air stew fuel stew how many turns on each 1
I mean screw
I thought my phone was broken but there was just no sound
Thank you so much
Glad it helped.
Thanks guy,
Hope it helped.
How do I know if it’s something else that’s wrong ????
Also at some mini cars.
forgot to clean the emulsifier jets... He had the, main out it was right there???
Thank you so so so soooooo much
Hope it helped ya.
@@-DIYPRO- yes
Nice video..but did it work?? Lol I was waiting on him to turn it back on
I should have shown it on my go kart ripping around the yard. Yes it runs great!
What if you use starter fluid but the engine doesn’t want to start at all.
Do you have spark?
@@-DIYPRO- I was going to ask the same thing. Yes, I have spark. Won't run even after squirting starter fluid in the air intake. Just a cough and that's it. Thanks
@@whistlershootingadventures3819 Hello. I was wondering did you ever find out what the problem as, and how you fix it ?? ( i have the same problem ) Thank you for help or reply in advance.
@@peedsii1991 It was a pressure washer and the problem was obstructed water flow. Easy to fix.
Excellent video and huge help. Thankyou
Glad to hear it!
Thank you!!!!!
No problem
Good video..i like
Thank you! Cheers!
Once again, you failed to check the level and condition of the oil before attempting to start the engine.
Agreed, Honda does put an oil level sensor on there and it won't start if too low.
Okay I’ve done the vavles regap n check the rods one wasn’t conntrd fixed that check for gas carb was leakin early fixed that as well check spark it’s there fuel going to the carb not the engine so guessing carb clean which only thing I haven’t done ran at the trailer when threw gas down the carb carb spray start didn’t work but gas did Um so gonna clean the carb n let ya know how to goes just annoying didn’t seals new cams everything just to be like no spark at all lol gets spark just no fuel
Did you end up cleaning the carb? Did it work?
@@-DIYPRO- not yet I’m try to that tonight if I get the time I ordered a new one anyways cause the left side bolt hole shoulder is broken n fuel screw is bent so may not work lol
@@-DIYPRO- gonna try it anyways just to see I’ll keep ya posted boss man
@@-DIYPRO- nah cleaned the carb didn’t do anything timing was off by the smallest bit out the old carb back on leaked like crazy put the new one on still leaked took that plastic spacer out stop leakin lol engine runs ok it’s a cruiser for sure no top speed at all a 12 year old be comfy with the speed lol gonna go out buy new engine this weekend lookin at a 420 with electric start to swap into it or lookin at a 190cc semi 5 speed kit to throw into it just thinkin on which way to go atm engine that’s in the mini bike smokes like crazy thought it was the two stroke mixed gas buddie ran in it before it was parked but nah ran it 7 times now easy 20 mins each didn’t burn it off check oil the oil I use it great I find just think the seals on top end need to be done now already did the bottom end so might as well rebuild it with the stage 3 kit for the cams atm wish I didn’t sell my first bike ran great had a Hemi on a doodlebug miss it buddie wants 150 more then I sold him it n it’s damaged to hell lol
je desirerais voir une video sur un moteur honda thermique gx160une fuite huile au nivaux de axe de la poliez
Ok I have a 390 with key start,cleaned carb,have spark,will not crank even with starter fluid also has fresh gas and oil..what could it be
Lots of them have low oil sensors and so if there is not enough then it won't start. Try putting a little more oil in it.
Ok will do. Thanks
Done that still nothing,i know the head gasket is blowed out,I'm not sure how long they ran the motor with the bad head gasket,it has no compression
@@juniorcook4094 yea that would make it not start!
@@-DIYPRO- I changed out the head gasket and still won't crank and no compression,valves set right..last thing I know is changing the piston
No spark
Check the wire, and ignition coil.
Also the spark plug of course.
Wowwwwww thanks you si much
If someone put diesel in Honda gx390?????
Did i miss something? Where does it talk about diesel in a Honda?
Why do you sound like this old tony ? If I’m honest I’d say this is defo this old tony
I don't hear it but you not the first to tell me that so I guess I sound a little like him.
@@-DIYPRO- I need help my Honda generater don't have power when I put Airfilter,it need to work without air filter
I already cleaned cuburater
I wasn’t soo lucky.
Mine’s going to the shop. First it’s going to get a new carburetor & second a battery powered electric start. Why the fucknuts had a pull start is absolutely stupid! Ethanol fuel only ruins carburetors. I’m not going to try your repairs. I know what the shop will say before dropping it off.
I ended up putting an electric start on this one as well, so much better.
dont crack the block

Double check!
Mobaile number moklo
To much waffle
We know where small engines are used. You don't need to tell us. Sigh.
You'd be surprised. My 4 year old didn't know that!
What if I take off the float bowl on Honda GX 120 and its only has drops of gas inside?...Thats my issue.
Then fuel is not getting into the bowl. With the bowl off see if the float is opening and closing (it's the plastic donut looking thing). It should hang down and be letting gas enter. Then if you push it up it should close off. Those get stuck closed and open all the time. I wish I could post picture in comments to show. Hopefully that makes sense.
@@-DIYPRO-Yes...needle valve with spring?...I am going to remove that and clean it up..also remove jet and clean...The bowl itself is super clean...no residue-coloring etc..like you said hopefully its just that needle valve thingy..
