Hitachi Carb

[jboulukos]

After endless tweeking, vacuum leak fixing, fast idling and anti-dieseling solenoid swapping, I am thinking of purchasing a remanufactured carb from national carburetor. The B210 carb for 1978 runs $149 plus $40 for core charge (not sure what that means). Anyway, my question is has anyone tried a carb from this company?

$40 for core charge (not sure what that means).

what that means is they want your old pos carb or you will have to pay $40.00 plus the $149.00 total $189.00, don't forget, there will be tax also. ;)

Thanks 420, I have 4 other carbs. I'll give them a rusted one without the anti-dieseling solenoid on it. We'll see if that will fly. Do you think it's a good try to get one of the carbs? I don't dabble too much on my own and labor costs can build up. My experience in Seattle was not the best as far as finding someone who can fix the carb and get me on my way without something happening 1 week later. I am now in Chicago and have my B210 in the garage away from salt. I just want to get a decent carb thats been cleaned and tested and operates above average.

sorry I don't buy much off the internet unless it's local.

 

There's Rat members that are more into the B210, maybe they can help you.

ive had success with national carbs

[KELMO]

Cores need to be complete when returned or you may get dinged for partial core credit or possibley the whole thing, just my 2 cents worth

[king bee66]

after rereading this post, if youve tried 5 different carbs and none have worked, maybe it isnt the carb that is the problem?

I bought one from guaranteed carbs in florida and it works just fine. Don't know about national carb, I know I talked to them but i think they said they didn't have one and I'd have to send mine in to rebuild and it would take a few weeks. Guaranteed got mine ready and to me within a week of ordering.

 

Do you know of an aftermarket air cleaner, or an adapter for one, that will fit our stock carbs?

I got a 4 or 6 inch (I don't remember exactly, it was about 8 years ago) cheapy aftermarket circular chrome air cleaner from Pepboys that fit the hitachi carbs. If I remember right it had a rubber adapter gasket to get it to the right size, I think it was for a chevy or something. I basically just measured across the top of the carb and went and looked around. The aftermarket ones will usually have a size range they fit.

[JustinB]

I'll check around. Best it seems like I can find is 2-5/8 and I'm pretty sure it's a 2-1/4 inch opening. Better measure again.

I bought my first B210 in 1980 (a used 77) and have owned at least a dozen of the them since. I have never found any remaned carb to be worth my dime. You would be a lot better off asking around and finding and old school mechanic to rebuild it. for about the same money. I f you think about it you are thinking of sending in your junkiest core, which is the same thing every one else does.....you r buying some one's garbage. Only so much life in any cast part, they can't all be saved. If you have a decent carb now, find some one you can trust it to bring it up to par.

 

 

That my friend is my two cents.

[ggzilla]

Or, buy a good used Weber for $100. One for a Datsun 620 or 510 will run pretty good without rejetting. You do need the right adapter plate for an A-series engine. You take the throttle lever off the Hitachi and bolt to the Weber and make a bracket to hold the throttle cable (or you can buy all these parts new for Webers).

 

By the way, a Weber won't run quite as good as a perfect Hitachi, but will allow the engine to make more power over 5000 RPM.

 

I bought a good running 1980 210 carb off eBay for $20. But many are worn out. So are some WEbers.

I installed the rebuilt Hitachi stock Carb into my 1.4 4 spped stick carb, and I have so many issues with the vaccum hoses, there are a few stupid selenoid vaccum valves tha seems to be shot at the electrical part,,they are made by Hitachi,,and no were to be finded.

 

I'm going Mad with the Fumes, I have an appointment to take it to Datsun Ville down in Burlangame Ca, two weeks from now, hope they can figure out the issue, or just let the Vaccum that goes to the distributor and remove the rest of those stupid hoses.

 

Sorry, I'm so frustated,,,th ecar runs, but I can feel esitation, and the Carburator seems to work fine.

 

Asta.

On my B210, it had a ton of carb problems when I got it. As we learned on my friend's B210, there's a cheap/easy fix for it. :cool:

 

If you can find a '70-73 Datsun 1200 carburetor, remove your stock carb, remove the jets from it, swap those jets into the 1200 carb, problem solved. ;)

 

The 1200 carb will bolt right onto a B210 or 210. And they are usually a lot cheaper than a Weber. Plus no somg, no electronics, no nothing. The one I used on my car hadn't been ran in 10+ years and still worked perfectly right away.

 

Swapping the jets is very easy too. Just flip the carb over and you'll see what looks like two 12mm bolts. They are actually caps. Screw them off, and with a flat head screwdriver you can screw out the primary and secondary jets. Do the same on the 1200 carb and screw the B210/210 jets into the 1200 carb. Takes two minutes to do. Just don't mix up the jets. :D

[El Guapo from Santo Poco]

well yes sound real easy, but htere is no 1200 Datsun arround that is willing to donate (sale) the Carb!!!

 

there have to be another easy way to plug the F^%4 lines,,I got most of them unpluged, away from the carb, I just lefted the Distribuitor Vaccum line because I know that tha's the only one that is needed to advance ..move the distribuitor cam....other than that,,there is a thing on top of the Carb that supossed open one of the trotle flaps...I think that one needs vaccum to function,,and I suspenct that that is the one tha's messing with me.

 

thanks for the advice do, if I find the carb from the 1200, I will swap it in.

[El Guapo from Santo Poco]

all right, I starrt to get a good feeling of how the Vaccum thing work, withc is part of the stupid emissions system on the car.

 

here is a link of what I'm reading it ilustrate real nice with images and wirted details.

 

hope is of good use for the others here.

this link wil ilustrate the trotle oppener thing.

thanks.

[El Guapo from Santo Poco]

ha,,I got it...I just canceled the main vaccum going into the intake manifold I put a plug on it, car runs clean, and great aceleration curve,,streight up....hope this helps others with this issue. until I find some after market stupid throttle vaccum electric oppener, and all the other gismos that make the car run cleaner.

 

I pluged the distribuitor to the higer vaccum port in the distribuitor,,so htere is zero vaccum at iddle, ( the vaccum port at the bottom of the carb has always vaccum ,,this is not good for the carb at iddle /timming issues.

 

good night.

Freakin' sweet, I had been wondering if you could do that, but didn't want to take the car down to try. Thanks!

Well, if you need one, they seem to pop up on ebay quite often. Heck I saw an NOS one go for $80 awhile back.

[El Guapo from Santo Poco]

Thanks Datsun freak, eventually I'll replace the selenoids hopefully I find them a some junk yard.

smog is due until late 2012 anyways.

[ggzilla]

That's a good idea. The 1200 carb is richer-jetted than the B210 carbs. I'm using an unmodified 1980 A15 carb on my 1200 right now, it runs great but has a small flat spot just off idle. But it gets good fuel econonmy.

[El Guapo from Santo Poco]

yea, that flat spot still in my carb right at the take off from a stop, but I just press the gass a few times and the flat spot desapears ,,,,,car runs great.

[Datsui]

Which weber would make a good replacement if a 1200 isn't available? I got some foreign bit of metal that's jammed my primary butterfly half open and I'm afraid I'll have to bust the butterfly to get it out.

[Nicholas7620]

I just looked at RockAuto online, they have a brand new solenoid for 15.22 before shipping.

 

GL with smog, I have to smog 6/12. :rolleyes:

[JDOM310]

I cannot find the step by step rebuilt of the stock Hitachi craburator that had been posted here on ratsun. Anyone remember seeing it? Could share a link? Thanks guys I keep looking and no luck
