how to adjust the carb and choke on a 1992 Daihatsu Hijet Minitruck 660cc JDM version ダイハツ・ハイゼット s83p model...others similar follow me on twitter / fupabox
My friends is a 94 1000 petrol engine running rich. It seems to have a manual cable choke. Needs full choke to start it and stutters and stalls unless the choke is out for a long time. Is there a mixture screw on the carb or air bypass jet? when it’s warming up under choke. Isn’t helped by radiator fan being wired to be always on. Probably needs a new sender unit. I believe it’s supposed to operate at two speeds depending on temp and shouldn’t come on straight away.
hey ! Can you answer a question for me. The little choke coil tension spring. Where does it attach to the lever? towards the tip or closer towards the shaft? I can kinda see it in the video. It looks like it's on the outer part of the linking, but it's blurry and hard to see. mine looks like someone bent it.
Hi Fupabox. Thanks for sharing this video, very helpful, to me at least. I have a 550cc version of this truck and I have made a bang up job in trying to tune it. First off, I had no idea what the adjusting screws were adjusting. I'd do ok with a regular downdraft carb but this would be a stromberg or skinner-union type if I'm not wrong. I thought the cold idle adjust was the idle speed adjust (confused me to see there was another one off to the other side of the carb), the warm idle speed adjust was presumably the fuel mixture (judging from the fuel hose close to it). I noticed that the choke flap would be at a small opening at idle, and opened up as more air rushed in with the throttle opening. I assumed this was to help draw up more fule to the venturi when the airspeed was low. Anyways, my engine has been idling unpredictably since. I got it to a point now where the engine speed would "gradually" come down to an idle, but would stall if I kept it there for long. Tricky business driving through stop and go traffic. I had thought that some sort of air or vacuum circuit and been wrongly routed or improperly condemned, and I did find some vacuum leaks at first. I might have to actually remove the carb from the engine and take a close look, but thanks again for your vid I think I'm now more able to make a more accurate attempt 2nd time around.
Hey +Chuddlebuggy did you figure out your carb? I have the same 550 cc engine. It has a new (Aftermarket?) carb, but I don't know how to adjust for bad cold starting. Any pro tips? For instance, mine does not start on a high idle (2000 rpm) at all, so I maybe need to figure out why. Probably what's wrong, as a low idle simply makes this thing hard to get going at all. Mine tries to idle almost silently, presumably down around 600 rpm (no tach)
@fupabox Thank you very much. i will try to get a suitable replacement. i will let you know how it works. just out of curiousity do you have any schematics to show how the vaccum for the mini dump truck model s83p. my electronics all come on but the vaccums dnt work for the 4wd. non of them neither does the sudiff lock. all the switches are giving current but still no vaccum. some of the hoses arent connected. NB this is for another vehicle i have two. one dump truck an one regular truck.
How can I contact you about more info? My s83p does not like to start unless I cover the carburetor with my hand when it is the warmed up. I understand that if it was cold then I could have a choke issue. But why do I need to cover the intake when it is already warmed up?
@fupabox thank you i will check it an let you kno how it goes. but first. on the engine block itself there is a cylinder like thing which all the hoses are connected to, it is broken an is no longer connected to the engine. could that be the problem?
hey I have a 92 S83P and I had to rebuild the carb without directions and I thought I did a great job on keeping track of my vacuum line placement but now when I start the engine I start to get a hissing sound from one of the lines after about two minutes of warming up and then the choke idle starts rising with the hissing sound....I cannot find a vacuum diagram anywhere on the internet...Any help I would be grateful for.
Is it possible to adjust thos carbs with vaccume gauge ? I have CB41 engine and it pain in the ass to adjust it, i bought new carb but i think its for S110 or something it almost identical but it dont have as much vaccum hoses as my old one, it has choke on vaccum this one does not. Regards,
yes you can . Just hook a vacuum gauge to the carb after warming the truck up ..then adjust the mixture screw until you get the highest smooth vacuum reading
Have been working on mine and as you suggested, the choke is stuck or at least very tight without freeplay in it like you mentioned it should have. What are your recommendations to get it unstuck and freely moving?
You can take the butterfly off from the choke and then removed the tiny little pins that hold the choke lever mechanism in place. Then remove the choke shaft. Clean it up and apply some lube.
@fupabox the idle speed is still high. i encountered this problem when driving. as i stopped the vehicles the engine raaced ahead then rapidly dropped down finally cutting off. i checked the caburattor, left it over night then started it back. the same high idle. at both hot an cold engine temp. when i adjusted the throttle it dropped very low an raced back up an down uncontrollably an keeps cutting off. it is nt holdn or taking any tuning
i was wondering if you know wich a carburetor can i adapt for my 92 feroza since mine is damaged and im from Ecuador and here there are not original parts for this car.... i hope you can help me... i you know a carburetor that give the feroza a little more power too that will be awesome
nice work! i have a question. is there any restriction plates or anything on these trucks. i have a 93 and in forth gear it is pretty much gutless.is there anyway to get more power or torque out of these. thanks
wax pellet type choke enrichment in the carb is likely stuck. A lot of Japanese JDM vehicles never get coolant flushed . The coolant passage into the carb choke is very small and can get clogged. You can try blowing out that small line with compressed air , Also likely that the float seat is gummy if you are using fuel with ethanol in it, Try 1/2 bottle of seafoam in the tak with a full tank of shell v power premium . That combo will usually clean the gunk out that ethanol can create. If not seating properly the float will allow fuel to drip into the intake and flood the truck every time after sitting till cold .
Fupabox, you may have seen my post on the forum, but in case you didn't, how do you keep the truck from dying when warm and you remove your foot from the gas pedal? Is that just an adjustment with the big screw (warm idle adjustment)?
I am working on a 92 Suzuki that will not idle down. It has been set up for a good bit. Any suggestions to what I need to look for? Once the engine warms up it diesels really bad when I key it off. Thanks in advance.
Great video! How can i find out how to remove the ignition barrel to get a key cut as i just bought one but the key was missing. Maybe you can help as a Google search didnt get a result. Cheers Bernie NZ.
if you search for dihatsu charde ignition removal you should be able to find that , and it should be the same . I have never removed one myself , so unfortunately I have no info for you. Also check piaggio porter ignition removal. Same vehicle built under license in europe
hi fupabox I also have a s83 that I would like the carburetor vacuum lines sorted out..could you please send me a diagram?and could you tell me what those cylindrical units are that look like non return valves?..Thanks much
Thanks for this. I have a racing engine on start up. Won’t run smooth till after 10 minuites, then sounds good. Can I follow this on Diatsu romahome 13 hundred engine , 1999. Thanks
It is thermally controlled by a small coolant line that goes to the carb...when hot coolant makes a bimetallic spring move , it should open the choke.. the usual culprit is a clogged coolant line to the carb
Off Topic Question: We have A 1990 dAIHATSU hI-jET 4X4 Manual Shift 659cc Engine Chassis#s83p-005848 I'm needing a iol dipstick. Can You or anyone direct me to where I can buy another? I have searched to A Dead End @ every lead I get. Thanks in Advance!
I haven't worked on one,but from the info I've seen they are pretty much the same. Japan allowed a jump in maximum CCs from 550 to 660 for Kei class vehicles. Most manufacturers just increased displacement by boring out the cylinders . The carbs would have larger needles , and possibly bigger valves . I think the 550 engines were all sohc , and the 660 was available in both sohc and dohc with 2 or 4 valves per cylinder . the 550cc was called the EB series and the 660 was the EF
@@fupabox Thanks. Some parts are similar or the same, but as you know that's hard to verify. Hey, I just found out that a new (aftermarket?) carb for my 550cc was installed by a previous owner and he didn't hook up the auto-choke. It seems to be a mechanical action coming from a heater hose that detects engine temperature and chokes it?!? Mine has no choke cable at all, and I finally figured out why it's hard to start this thing!! Where does the choke cable go, how does auto-choke work? We are flooding the engine so bad that fuel goes backward into the intake with these cold days.
@@fupabox Ok, I knew about the wax thing, and I knew that cars of that era used a wax-operated "door" in the snorkel (air intake), but I thought that the Daihatsu auto-choke had an external rod to operate the choke. But now I think I see a more direct connection where the wax moving part is internal and connects to a part of the original carb. Since my truck has an aftermarket carb and a cable-operated choke, I was wondering about whether there is a way to automate mine. If not, I was going to try a choke cable for a lawn mower or something so that the choke can be manually operated by the driver.
Hi there fupabox - great videos, they have been very helpful for me. Have you come across a service manual for Hijet trucks? Could you point me in the right direction? Thx!
online manual should be downloadable from this link .. make sure the engine size is appropriate for your model because the old hijet was sold as the Piaggio Porter for many many years with the same chassis,body and drivetrain ..but different engines shareasale.com/r.cfm?b=1003712&u=1635518&m=49176&urllink=&afftrack=
Fupabox - thanks for the tip. I looked through the list, but it wasn't clear regarding the motor. I have a 1994 Hijet S83 with an EF-CS motor (4-speed), 659cc. Any idea which manual would cover that truck? Thanks again.
Thanks for the very helpful video. I have an S110P but it's probably similar. Thanks for your MiniTruckTalk forum posts as well. Very helpful!
Thanks . I miss the little green devil and all the cool people on the forum . On the look out for another because I just enjoyed it so much .
great video buddy you are about the only one on here that actually got to the point and wasn't a idiot thanks 👍 😀
Thanks for this man!! Just got an s83p... Helps me a ton! Thank you!!
Great video! My truck stutters at the beginning of each gear then takes off. Often times it will stall out while it idle's. Any thoughts on a fix?

I'm not familiar with that engine , possibly the same ..
Can you explain what opens the choke after it warms up?
It is thermally controlled by a small coolant line that goes to the carb...when hot coolant makes a bimetallic spring move , it should open the choke.. the usual culprit is a clogged coolant line to the carb
Mine is running rich; I was hoping for something I could adjust to lean the mixture..? (not at idle)
likely your choke isn't coming off fully 4:10
@@fupabox Good point, Ill watch and maybe do some lubing. Might need to do some cleaning first, I blew the dirt out but didnt brush anything.
@@natehill8069 check the coolant lines that run to the choke as well... if they are clogged the choke can stay on and cause rich running
@@fupabox Plus I rarely drive it more than 5 minutes at a time so the water never gets hot. I wish it just had a simple cable-operated choke.
