flyerdan Posted September 23, 2019 Report Share Posted September 23, 2019 Rock auto has them, I'd imagine that Autozone and Oreilly's will have them as well. I'd check, but you have to add a vehicle; at Rock you can search for anything, whether it's in your list or not. Wish the others would adopt that. 1 Quote Link to comment
vicdat Posted September 23, 2019 Report Share Posted September 23, 2019 Walker used to make a complete kit... 1 Quote Link to comment
Clint760 Posted September 23, 2019 Author Report Share Posted September 23, 2019 Went through parts geek and serched for the specific vehicle. Thank you Quote Link to comment
datzenmike Posted September 23, 2019 Report Share Posted September 23, 2019 90% is just cleaning them. 7% is adjusting the settings. None of the jets and bleeds or gaskets wear out so the last 3% is the accelerator pump. Throttle shaft can wear but not much you can do about those. 2 Quote Link to comment
Clint760 Posted September 23, 2019 Author Report Share Posted September 23, 2019 The previous owner told be he lost a little plastic tube that had something to do with the float and made his own but he said thats why it's probably having issues . Hopefully that part is in the carb kit. Quote Link to comment
bilzbobaggins Posted September 23, 2019 Report Share Posted September 23, 2019 Might have lost the spacer for the float? 1 Quote Link to comment
Clint760 Posted September 23, 2019 Author Report Share Posted September 23, 2019 Yes . I haven't opened it up yet but that is the way he explained it you are correct. Quote Link to comment

If thats all you need, im willing to be that someone on here has that little teeny tiny thing and would be able to hook you up. Might even get by shipping it in an envelope for however much a stamp is these days. Might place a wanted ad if thats what you need. There are a lot of folks who dislike the factory carb but who love to help keeping datsuns on the road. I havent one myself as I lost the one to my spare carb (duh huh). 1 Quote Link to comment
Clint760 Posted September 24, 2019 Author Report Share Posted September 24, 2019 I'll just have to take a look and see inside . Thank you for the suggestion! Quote Link to comment
banzai510(hainz) Posted September 24, 2019 Report Share Posted September 24, 2019 I hate those stock carbs as it’s a rubix cube ready to explode if they work they are great Quote Link to comment
datzenmike Posted September 24, 2019 Report Share Posted September 24, 2019 It's a tiny copper or brass tube about 3/16" long. It sits on the pin the float slides on between it and the glass front. It just prevents the float from sliding sideways towards the glass. Number 47 below 3 1 Quote Link to comment
Clint760 Posted September 24, 2019 Author Report Share Posted September 24, 2019 Cool! NowI just need to take it apart and see what he might have used to replace the original little tube. Even though I have a carb kit on the way I have a hunch the gas was pretty old too . 1 Quote Link to comment
datzenmike Posted September 24, 2019 Report Share Posted September 24, 2019 Anything will do. Snip a small length off copper tubing. Cleaning the carb is 90% of the rebuild.... and don't forget a new fuel filter every 2-3 years. 2 1 Quote Link to comment
Clint760 Posted September 27, 2019 Author Report Share Posted September 27, 2019 So I live out in the middle of nowhere. I have to improvise sometimes so as I peeked in there to see the previous owners fix a little peice of weedwacker fule line and it happend to be the same diameter of those little vacuum lines at the base of the carb . So you guessed it I just cut a little piece of that vacume line pipe off . I plan on gitting rid of all the emissions stuff anyway. I thought I was going to have to take half the emissions stuff off to get those 4 bolts off lol .I was stubborn and just used one side of needle nose pliers to rotate that front right nut . 1 Quote Link to comment

Number 47 below It amazes me how complicated the the stock carb is. here is the explode view of the Weber DGEV 32/36 carb. These are simple carbs. 1 Quote Link to comment
datzenmike Posted September 28, 2019 Report Share Posted September 28, 2019 It sure is Charlie. But it has to have low emissions, good compromise with power and mileage, fast warm up, idle smoothly. Provide a ported vacuum for the EGR and have a vacuum operated secondary that only opens when needed. Did you know the Hitachi accelerator pump has a built in leak back to the float chamber? If you step down slowly most of the discharge that's not really needed pushes back and isn't used. If you step down firmer, which can cause a hesitation, the discharge is larger. Yes very complex because of all it has to do. If just mixing gas and air.... a Weber will do. 1 Quote Link to comment
Charlie69 Posted September 28, 2019 Report Share Posted September 28, 2019 (edited) I pass emissions every 2 years with my Weber. I have a significant power increase and I can pull 30 MPG out of my Weber if I drive it nicely. I did not have any problems with warm up in the winters when I had it in Battle Mountain Nevada. With most people simple is better. I find the Weber is one of the simplest carbs manufactured to this day. My EGR on my 86 works just fine with the Weber.

datzenmike Posted September 28, 2019 Report Share Posted September 28, 2019 The Weber flows more and stock carbs are on the small side so there will be a performance gain. Even a Micky Mouse watch tells good time. 1 Quote Link to comment
Clint760 Posted September 29, 2019 Author Report Share Posted September 29, 2019 I do have a webber on my other 620 I originally got for parts but I can't bring myself to take parts off it . I think eventually I will . 1 Quote Link to comment
Charlie69 Posted September 29, 2019 Report Share Posted September 29, 2019 Once you run a Weber you will not go back to Hitachi! Oh unless of course you are Mike! LOL 2 Quote Link to comment
Clint760 Posted September 29, 2019 Author Report Share Posted September 29, 2019 I guess the needle valve was just stuck.I took it out and put it back in . Plus I had the front plate upside down maybe that was keeping the float from moving oops. 1 Quote Link to comment

Marv Posted October 1, 2019 Report Share Posted October 1, 2019 Hello and thank you in avance. I have a 1982 s10 with a Hitachi dch340; it was a refurbished unit installed in 2015. And I am still not able to drive the truck nicely. I have set the idle and mixture screw several times, has new plugs, new wires, new distributor cap, newer fuel pump, and 2 new acceleratiom pumps. So the truck Idles nicely, compared to before when it used to backfire. I set the time to 6deg. Rpm set at 850rpm, but if I try to drive, it feels like I want to take off in 4th gear. I had it driving better before, but hesitated all the time when accelerating. Everyone says it is the carburetor, but not sure. It starts perfect, acceleration pump squirts nicely strong. But when in gear, it bogs down- I checked vacuum diaphragm at egr, and holds. I do have a bad muffler that exploded before I bought the truck, and the catalityc converter seems rusted thru. O sprayed carb cleaner and could not find vacuum leaks. Sorry for the long post. Any help would be appreciated. BTW, the truck is under 50k original miles 1 Quote Link to comment
