Today we are Working on the Honda WT30 Dewatering pump. This is a 3 inch pump powered by a Honda GX160. The issue with this Honda GX160 is that it only runs with the Choke on. At first I thought it was a fuel related Problem. This video series is to go about troubleshooting to see what the issue is. Post your comments on what you think maybe the issue.
bad carb?
low compression ?
valve issue ?
this will be the same if you have a gx120,gx160,gx200, or any other honda clone engine.

Great, thanks for not answering the problem!
3:24 that's your answer.
@@impactodelsurenterprise2440 and there’s your dinner
If your engine simply won't run the quickest way to get somewhere is spray a flammable into the air intake like carb cleaner or starting fluid and if it still won't even fire for a second you have no spark. If It does fire then your having a fuel issue.. disconnect the fuel line from the carb and make sure its flowing out nicely. If not then most likely just need to clean the carb, its not difficult just take photos and remember exactly how everything came apart, note which side up or down on any little parts you remove.. stay organized and don't lose anything, Goodluck :)
I had a problem with a GX160 only running on full choke, that's what brought me here. Problem solved: two words, wife diesel.
+sam coleridge seriously, how well did it run on diesel lol
Like my old friend says... womens are the most destructive thing after the nuclear bomb...
I think my wife did the same thing to our ride on mower...
sam coleridge thanks you solved my problem.
@@Skyfinder007 so what did you do, poor diesel in in and just let it sit ?
where is pt 2? can not understand the sequence in any of these uboob vids.
Comes for answers * gets asked to what the answers are *
had the same problem. replaced the carburetor gaskets and fixed my problem.
Save yourself time and energy when working on a motor with broken recoil use a high power drill or impact on the center bolt just be careful for a back fire also use a 6+ inch extension and make sure socket can’t easily come off and fall onto the crank
Impact is a great way to break the end off your crank. Drill is ok.
@@dwizdofoz. I broke one trying to use an impact to start a small engine like this once
Iv seen guys snap them right off be careful especially with him dumping raw fuel into cylinder creating a prime condition for hydro lock
no danger of the socket not letting go when it starts?
@@schoon111 lol 100%. Sometimes it works, sometimes it doesn’t
Thanks for the tip on checking whether or not the tank had airflow. It inspired me to check my clogged breather tube (predator, not honda) and my engine is running normally again.
solved my problem gas cap would not vent runs fine with cap off
I have an old Honda GX200 motor and it wont run off of choke for more than 5-10 minutes of riding; cleaned the engine, carburetor, and even the gas tank & bowl; it idles fine, but wont give me full gas “sometimes”; the throttle can give me a little bit of rev, but too much rev and it will shuf off. Any ideas?
gasket leakage
The round part of the choke lever fits in the fuel hose as a plug!
nice. thatll come in handy
Wish I would have known that when I took my predator 212 carb off
@@jeffsilverman105 I work on my bikes a lot, it's a cool little trick for sure!
@@JonLasaga....but next time! Maybe you'll open up that carb and swap in a 140 emulsion tube and a gx340 jet. Great performance combination for any use of a 212.
@@fatbuddycat yeah it will be good for next time my engine has been acting up and it dies with any throttle when its warm only and I couldn't find anything wrong with it when I took it apart today so ill be doing it again soon. Not sure if ill swap the tube though since I already have a bike carb for it i just have not put it on yet because I dont have the intake for it.
I just finished replacing a bunch of stock parts with upgraded replacement parts including new carb new fuel tank new jets even a new head all together and it only wants to stay running with the choke on still. So how can i have any of these problems if everything is brand new ?
@@SunriseLAW That's what mine's doing too. I'll put the choke on and start it and if i'm lucky enough to keep the engine running for longer than 10 seconds after i turn off the choke the engine surges like it wants to put out some good power but then after a surge in power it wants to stall out and die when you try to give it gas. I don't think they're supposed to do this lol I've never had this problem before it's just a pain in the ass to try to pin point the problem. I played with the brass air/fuel screw on the side of carb and that didn't solve the problem and then i made sure all the carb gaskets were on properly and it still didn't work after that so now i'm kinda scratching my head wondering what to check next. Maybe i need to take carb off completely and take it apart to see if it needs a cleaning and maybe replace fuel line cause i know there is a slight leak on fuel tube but i put a slab of Flex Tape over the little tear in the tube where it was leaking from to stop the leak but who knows if that is the what's causing it or not. There's so many different things it could be and i am running out of patience trying to figure it out lol. Did you ever get your stalling issue fixed other than keeping the choke on 1/4 of the way ?
Dude it's not the fuel cap 🙄 You should be able to take off the fuel cap off without causing the carburetor to leak, that's just common sense. Have you ever seen any other carburetor leak every time you take the fuel cap off I mean that's ridiculous.
I've got the same problem!!! By the way, the choke lever has a nodule the same diameter as the fuel line so just pinch the hose and pull, then attach the choke lever to it. No leak ;)
My gx 630 starts but shuts off but stays on with choke on
Not gonna lie in the first half of the video you kinda comes across as someone who knows what the hell they're doing then by the end you're asking us to fix your engine for you. This aint it chief.
The screw from the float bowl actually fits in the fuel hose as a plug in the gx390.
The choke lever also has a knob that fits the fuel line.
That is gold...thank you sir
it's going to run lean if the carburetor to intake manifold gasket is bad yes I also agree with the gas cap a lot of people don't know that the gas cap has vent holes and the gas cap very good video
Same problem. Turns out the linkages on top of my carb which control choke were stuck.
I pulled the bowl and cleaned out my pilot jet. Ran great. Another motor runs but not at full speed and when i pull the choke, it’s runs tHe same. No worse. Shouldn’t the choke being pulled at full throttle cause motor to Stumble? Mine still runs exactly the same?! Clogged jets?
Whats the final solution on this problem with the choke? I have the same setup with the same problem. Head gasket? How are u supposed find the next video w/out a link posted here? I followed all the others i could find and dont see a solution!!!
all the videos with this motor are in this link for the playlist th-cam.com/play/PLxtlXKgrDXMWP6CEobuU9hdUicN8mr4oY.html
Clamp the fuel hose with the choke lever its made to do this
there is a screw on top of some carbs that tell how much gas is flowing if you have this type turn counter clockwise 1/4 turn will in grease fuel flow check this out before you start hunting and pecking the tbl.
My same engine doing same thing. I cleaned carb and cap. What was the issue? I can't find part 2
Lack of fuel for sure. Should be able to open up the jets to over fuel it as well. If not the carb emulsion tube is plugged.
+Steve Rob that's what a person would think and it' seems very logical, however wait till the next video.
Well that's lame no link wtf
Don't need a new carb. Just clean it and Hondas will run perfect again. I've fixed many Hondas.
I have a Honda gx340
11hp
I bought a new carb because the old one was cracked, so I put that on replaced the gaskets, got a new gas line and gas tank. I put all those on. It will only run with the choke on, as soon as I turn it off it dies, and it won't idle correctly. Anything you would recommend I try or check?
Had similar issue turned out to be sparkplug
Reamed carb with a welding torch probe, drained carb bowl, added new plug, changed oil and air filter. It was a clogged carb jet. 10 min fix
the problem with the carb is the idle jet which is plastic and it's located under the idle adjustment screw. Get a new jet with the orings the orings in an old carb almost always rip.
No shit, my motor would not idle. Took the carb off 10 times at least, finally used silicone gasket maker on all faces and made the nuts extra tight. F#*k me first pull and runs and idles like a new motor, so I think if you need the choke to keep it running, it's a gasket leak as long as all the fuel jets are clean and the governor is set right. Cheers to all the comments to give me ideas of what my problem was.
Pulled the starter cord right off
I'm in a similar predicament
Same for 2023 cars & trucks. The fuel filler cap lets air in! The amount they let out from pressure "Does" change. Stamped on cap or sticker, "Caution" May spray fuel was seen on 1960-70's cars. Carbon canister allow air to vent to atmosphere, but capture fuel. The pressure out was 1 PSI for decades then changed to 2 PSI so if tank pressure got to high. 10+ years ago, inputs from timer, air temp and time driven requires "Engine-Off, Natural Vacuum" helps the fuel tank pressure sensor sends info to the PCM 20 minutes after its shut off and eating dinner. This detects tiny leaks, not small or large.
Caps have to be tested and aftermarket caps with Keys to keep that expensive fuel from being siphoned, all fail. It take run time and temp before these test are run, so not the next day but still!
DK, ASE Master Tech since 78, retired
Fuel cap vapor lock 🔐 🤣 😎
Another channel is telling me it has to do with ethanol
People need to realize that one persons problem is not the same for everyone. In this situation the cylinder sleeve was scored causing low compression
Like my girlfriend ,only run when choked...!!!!!!
Figure it out? M y 6.5 doing same thing
If I've learned anything over my years is that more of them like being choked than don't. So go for it don't make her ask.
Mine didnt start so I put predator 212 carb on it and turned the fuel halfway on and it ran fine
What was the fault? 8 years on & no follow up answer
there is a whole video series on it
Vacuum leak
Full choke whould suck gas from the tank , can't run normal if not enough air gets into the gas tank to replace used gas . Higher vaccum would suck just enough air past the restriction to allow some gas to get to the engine
You have way too much fun...... (sarcasm), sometimes small engines are a pain in the ass
+roguesquatcher I dunno why but I love working on small engines
dumo2043 It's been awhile since I watched this vid, but that is possible on those Honda carbs, they have a slight dimple in the bowl so the float has room to move, if not lined up the float would be jammed shut
dumo2043 did you visually check the jets and verify float is level when closed in the up position? Sounds like the engine is starving for fuel
dumo2043 I had an 8hp Honda that would drain the gas tank into the crank case when stored, even after replacing the carb. They also have problems with the "low oil" sensor, but normally they don't start at all if those go bad. Honda's can be a pain occasionally
My engine is cutting off when I turn off the choke I try everything like cleaning the tank an cleaning the caburator .what else can go wrong there?
I had issues with the fuel cap on them motors. was it still starving for gas with the fuel cap off?
+john d yes it was stay tuned to the next video in this series
Terrible
plugged needle valve
You didn't solve the problem buddie
i have a briggs 15c107-0014-f8
runs smooth with choke 1/2 way
cleaned main jet / emulsion tube , soaked carb body
Did it run well afterwards?
@@murphyking79 NO STILL SURGED , Ran smooth with Choke Partial on - Believe it or not !!!, RAN with " Mechanic on a Bottle " from Home Depot and CLEARED OUT !!!
the STUFF Does Work
I have the same problem too.I took carb off honda push mower that ran well but still same issue.I.m determend to check the valves and compresson. something else that shouldnt be over looked Larry
Put on new gaskets adjusted governor, new plug ????
Is it me or was the govenor set a little high?
ITS RUNNING TODAYWHAT I DID WAS GOT A TUBE AND BLEW IN THE AIR HOLE IN THE ENGINE. MAYBE THAT DID IT I DID. SPRAYED CARB CLEANER IN IT BEFORE SO I MAY HAD NOT HAD TO SPEND 85 TOTAL FOR A NEW CARB. I GOT THE MOTOR 10 YEARS AGO AND ONLY PUT OIL AND GAS IN IT . I NEED TO GET A NEW PLUG FOR IT THIS SUMMER. TOO COLD TO RIDE MOTORBIKE NOW, GOING TO 25 BELOW TONIGHT
I have had the same issue with that motor. I put treated gas in it with stabil and it started doing better.
It's sucking air around the black spacer between the carb and the block
You cant leave these engines with gas in them for more than a month without risk of ruining carb. The good news is the carbs are under $20 online. Don't mess with trying to clean the carb, just install new one and go on.
Amen to that
Rick Parker Blame the ethanol added to the fuel. it doesn't do well with brass/ copper parts.
I’ve been using sta bill fuel stabilizer for over 20 years never had a problem every 6 months if I don’t use the gas up I pump it out with a 12v electric fuel pump I dump it in the truck and I add new fuel with sta bil and run the engine I never leave carb dry
throw away nation, $20 can feed family of 3 for whole wee in my country, what is wrong with cleaning the carb
?!
Its not that hard to clean the carb. If you're lazy, just put acetone in the gas and it'll clean it for you.
Hi what will cause the gas to fill up in the engine oil .the engine will run great but once left over night has will get into the engine oil a hole lot . Thanks
Possible float stuck in the open position, therefore flooding the carb and overflowing, draining directly into the cylinder then leaking past the rings and into the crankcase to mix with oil...or not. Whatever
I have a Baja warrior 196cc. It's starts but when I turn the choke off the bike will start to take off. How can I fix that.
Willie Covington your throttle cable is probably too tight. Only way that engines going to take off is if the throttle is open.
I have same issue
U need to adjust the carbs idle screw
Got a Honda GC160 5.0, and it doesn't idle. It's way too loud, deafening. Any help?
to adjust idle speed screw could fix this problem, as the throat is almost closed. this is what I think. but not guarantee.
Bit my carbs new and I ported the jets as well to get better flow but it still suffocates when I close the carb it runs normal with it on but I don't get my full range of speed
my gx50 honda engine will not run with choke off . i got a new carb still the same will not run choke off. gas from 9-15 16. engine 10 years old been very good same plug. has been used on a bike .
molegfgfgf sometimes it's not the carb but it's the gas. Trying cleaning the gas cap. Also try cleaning the air filter. Next try putting some zero octain gas in it. It's made for small engines. Also add some fuel stabilizer.
molegfgfgf it could also be the gaskets, also known as a vacuum leak. Try putting new gaskets on.
What if it will run only when choke is on but the ac power is not 220volts even the avr is ok???
Found my answer. Watch the video. When he unscrews the inner nozzle tube inside the carburetor, (where he takes a flat screwdriver and unscrews the post) I had taken carb cleaner to the fitting, and it seemed cleaned - but it wasn't. It was partially obstructed. Just look through it onto the light and see if yours is plugged too. Then I found that inside the nozzle tube was slightly plugged too. I sprayed carburetor cleaner through the hole and found that it comes through the carburetor but could not see where the exit point was from. I later surmised that it is coming between the two choke plates inside the carburetor. (there's two plates plied together, not one. There was no way I could clean between those plates with carb cleaner. So I re-assembled the carburetor and found that I was on the right track. It ran fairly rough in the "run" position, but ran. Tomorrow I am going to get a chemical cleaner such as sea foam or something and try to chemically dissolve the rest of the deposits between those two plates as I use it for tomorrows work. This is given that everything else that you can find is "good." don't forget to take the float off and clean the needle valve, and spray all the fuel ports clean inside the carburetor. Then use fuel stabilizer in the gas from then on.
It’s probably just running a bad air to fuel ratio I’d guess it’s to much air so just rejet the carb
U need to drill the lid n put an. overflow the fumes suffocate the the flow of the fuel line if u run an over flow it'll breathe better n you'll get Alot more low end performance
i had a problem with my car wash engine, working for a short while then stopping, what might be the cause...pump is working well
i had athe same problem the govanor spring came off replace or reatach all done
I have an old 22cc Briggs and Stratton motor from the 40s or 50s. I know that I won’t be able to find a car for it. It is fully restored, no rust, clean intake/original air filter. Only runs with choke on. Should I loosen idle screw? Since I can’t get a new carb and the carb doesn’t come apart very well. If you know anything your feedback will be greatly appreciated ! It’s the last step before it’s fully finished project!
check out Musti1 channel, maybe you will get your answer.

Could have spent a minute on the mixture screws.
Don't beleive this model has adjustments
@@kendogg619
Yeah they do, but they're designed in such a way that you can't remove them without filing off the tab that restricts any movement, the only way round this is to cut it off with a dremmel
Dude open the window for Christ sake dont let that monoxide build in your room
He didn’t get to make a second video because the CO killed him. Too bad he didn’t open a window
screen filter in carb is plugged or even muffler has spatk arrester that gets plugged
the choke lever has a plug for the fuel line them Chinese think of everything lol
??
That explains a lot!!!!!
I thought HONDA is Japanese, copied in nearly every detail by the Chinese apart from quality the first copies even carried Honda id so the only good idea was copied
What is the correct petrol (gas) to two stroke oil ratio for this engine,cheers.
+craig stone it's a 4 stroke engine
Hi jerry, i'm in the U.K. so our standard unleaded petrol wont run it, it only runs with two stroke fuel (unleaded petrol and two stroke oil)..
I've sorted it now its 50:1 ratio.
Not hard at all to clean carbs. Do the ones I have every time....
Hi anyone know why my gx160 backfires when I pull the cord it does not start but backfires out the exhaust?
timing is out. flywheel may have spun the key, valves need adjusting or cam slipped a tooth. Good luck I had the same problem and just ran these issues down, it was the valves.
Make sure that you have got no water in the exhaust and you can try and start it with the air filter off!, the spark plug may need replacing or cleaning , it is easy to see if it’s sparking efficient and make sure that the carb is not flooded and the petrol is not old or dirty
I'm Runnen one of those pedal bike engines mines 2 stroke does the Same
Plz make a video answering why the engine runs only with the choke my predator 212 does the same thing
managed to solve?
i had the same issue but putting in yamalube carb cleaner for 48 hours made it run like new
*(I have a Honda gx200)
Jerry, I have a Honda and Clarke generator with Honda gx160 engine, I have changed spark plug, ignition coil, serviced it, cleaned carb thoroughly and it still cuts out after a few seconds... the spark looks weak even though it's new coil and plug... sparks 1 out of 3 pulls if that, any suggestions as to what to try next... really stressing me out hope you can help!?
Josh Regis probably rich fuel mixture
Ibraheem Al hadede it was faulty oil sensor
Checked the distance of the spark plug?
Thanks for replies it was a fault oil sensor
I got a gx 390 it only runs on half choke
you need to clean up the bleed in the aluminum body very tiny use air and carb cleaner
Mark Heberling how.
@@vineetgupta6856 use a compressor
I have a Honda gx 160 and I'm trying to run nitro methane in it but only runs when choke is on
I see that you rebuilt it, but did you ever figure out why the engine was only running while on choke?
Yup there is a whole video series on it
i have a Mitsubishi 6 hp engine on a go cart i just bought, but the engine will not stay running for more then a second. what are some ideas on how to fix it.
ps. its been it has not ran in a few months, according to the previous owner.
Blake if you have time a carburetor problem are easy to fix only you really have to have time to learn how to fix them with my lifestyle i have played with all kinds of small engine's i never let it's beat me only sometimes i do have to Google it only not that offer only it be hidden jets in the carburetor be plug up you will need a bread ties to clean the small holes in the carburetor also some carburetor cleaning and make sure that you have a red tip on the carburetor can because you have to spray inside all the jets you gonna need a air compressor too to blow out all the jets hold the air tool close as you can as you shoot air into the jets holes i always use water and degreaser with a spray bottle first before i started from the beginning wash through the carburetor outside and inside and use my air compressor to blow it dry outside and inside to get rid of all that gunk then i starts cleaning the carburetor don't use cold water use kinds of hot water when you first start to carburetor take it completely apart first i mostly used commercial degreaser because the job i work on get it by the five gallons bucket
Blake remember to use a red straw that's comes with the carburetor cleaning and make sure it inside each jets holes and make sure that you wear eye protection because that carburetor spray will be all in your eyes and that's not a good feeling
That boy isn't getting enaugh gas
My boy goes nuts when I open the choke compeletly which leads me to believe there is a problem with air fuel ration
Nope that wasn’t the issue
clean the air bleeds inside the carb
Wjy
I think it was the petcock
Had the same today on a pressure washer. The fuel smelt odd so when I drained it I noticed a residue on my hands from the fuel. It turned out there was diesel mixed in with the petrol. A full cleanout and left to run with aspen 4 sorted it out.
Intake leak
what about a govinor spring
*governor
"governor"
Complete waste! Looking for answer to the problem.
The video is part of a series but it seems your not smart enough to figure that out
The carb mount posts unscrew from the motor body. Remove left on and carb will slid out, you don't have to unmount the motor from the frame.
You sir deserve an award. It’s been driving me insane
old video, but I just want to add that a vacuum leak will do the same thing. Did you put new gaskets under the carburetor?
Old vid and old reply but your simple statement made a world of difference for me. Thank you Mr Posey.
@@condor-6-one83 witch one did you replaced ?...the one in between the engine and carb or between carb and air intake ?
I have a problem with the same engine gx200 it doesn't have a needle idle mixture on the side could that be the reason why it won't idle on run
+Nick Donato i would do a cylinder leak down test to see the health of the engine
how do I do that
