Broken piece in carb help!

So as you can see the one of the pieces holding the float bowl in place is broken. I have no idea how long it has been like this but is there a way to fix it? Will a dot of super glue work or will the gas just eat it up. Or am i completely screwed and need to get a new carb?

EDIT
hitachi carb of 1982 xj 650

 

If there was supposed to be a picture there, it did not come through. Are you talking about the 4 screws that hold the bowl on? or are you talking about one of the pillars that hold the float on? If it is one of the screws you may be ok, if it is one of the float pillars your pretty much looking at junking that carb. If it is another piece there may be another solution. Also what bike are you working on so we know if it is a Hitachi or Minkuni carb?

 

I think there's a problem with Gmail at the moment, just pasted the link in my address bar & got a 404 error message.

May be easier to use photobucket?

I'm hoping it's just a screw :?

EDIT-: google's back!

Sadly that's the float pillar and the carb body is scrap (well they can technically be TIG welded but cost would be prohibitive unless you know somebody who can do it at work on the Q/T? Sorry it's not better news :cry:

 

osprey sorry about the picture i think it is up now right? .. and yes it is one of the float pillars on a hitachi carb off a 82 xj650 maxim

 

I just edited my post above when I saw the pic, sorry. And as osprey says, if you put your bike details in your signature it helps with specific solutions

Welcome to the forums by the way

 

Yes, Like bloke said that is usually terminal on the carbs. Don't just leave it like that obviously since that can effect your fuel levels and possibly allow your carb to flood the cylinder. You are probably gonna need to look on ebay or craigslist to see if anyone has a rack or something that they are selling. You can also put out feelers on the forums here as some of the members have a few laying around and may be willing to sell/trade one. And as far as using super glue or something similar, That is pretty much just putting a bandaid on a bigger problem.

 

ohh no! =( this is horrible. Where can I get a new carb

 

Where are you based? That's another thing to add to your profile that helps when you're in this situation. I've got spare hitachi 32mm bodies but I'm in England & guessing you're in USA???

As osprey said Check out ebay and stuff, also look at the for sale/wanted forums on here too & maybe post a wanted ad, being sure to say which carb body or bodies you need 1 2 3 or 4 (they are different)

 

Try putting some feelers out in the Sell/wanted section of the forums. I'm sure someone may have something. You could also try sending a message to len at XJ4ever (click the link in the upper right of the page) I don't think that he has any but you never know. He has alot in his arsenal. Other than that you would have to try ebay. You would be looking for a Hitachi HSC-32 (wizards correct me if I am wrong) carb. More than likely you will find them on ebay as the whole rack. Good luck with that one, unfortunately it does happen and that is why in all the forums about cleaning your carbs around here you see them mentioning to protect those pillars at all costs.

Edit: Also what Bloke said.

 

Aluminum Body carbs, right? Know anyone that does some machining and TIG welding? Has to be even so the float isn't cocked and the float pin rides free, but there's no reason it has to be the same shape.

 

JB-Weld has worked on other carbs - - the mating surfaces need to be COMPLETELY clean. Maybe this will hold you until you find a replacement.

 

i did some further research and heard of people using gas tank epoxy. As for now im going to try that for a fix and if not i will just replace the rack. only like 100-200 on ebay

 

I've used a good 2 part epoxy tank sealer to glue the foam carb floats back together before and it's held really well. I know the stuff works for plastics, but I'm not sure about metal to metal adhesion.

 

I guess it'd work, since it sticks to the inside of metal fuel tanks?

Good luck with the temporary repair. I guess you're not in the UK? or you'd be welcome to one of my spares they're wrong for my bike anyway.

 

Just want to ask you Bloke how would I tell the difference between Hitachi 33 and Hitachi 32 carbs? where do we measure that? I have an Hitachi carb spare rack but I can't tell for sure what model it is.

 

IIRC the best place to measure for telling which is which, is actually the *outside* diameter of one end or the other.

Len PM'd me some dimensions a bit ago when I was rebuilding my rack as I put a vernier to mine & the inner diameter of the engine side was close on 33mm & I got excited, but then found the true 33's are even bigger!

EDIT-: from chacal


Hitachi HSC32 intake throat ID: 32.60mm
Hitachi HSC32 intake manifold flange OD: 37.95mm
Hitachi HSC32 airbox boot flange OD: 50.10mm


Hitachi HSC33 intake throat ID: 33.70mm
Hitachi HSC33 intake manifold flange OD: 39.05mm
Hitachi HSC33 airbox boot flange OD: 50.25mm
---------------

Also, I found that on the outside of one of my float bowls there was still a faint remain of the HSC model code printed/etched on the bottom side, guess that only applies if your carbs have the original bowls though! And the HSC33 have an extra hole above the fuel rail holes, between 2-3 and 3-4, for float bowl breathers.

 

Hum, mine are definitely HSC32, sorry!

 

Ah well TY for looking They're a pain to find I think as it was mainly 700N's that had them.

Maybe Trav would need them if you're selling? Be a better option than sticking the pillar back on, don't think I'd be able to ride a bike with carbs stuck together like that without a nagging feeling & panicking at every little pop/misfire/stumble :?

 

I would have been ready to sell the rack to you (if I had a 33 mm), but now that I know I have a 32 mm, I could use it on my '83 MAxim 750. If I ever realize soon that I can't have this bike to run properly because it needs a ring job or even worse, i will be more than happy to offer lots of parts here on the forum!

 

Ah yes forgot about the project bikes, I was thinking you wouldn't need 32's as you got the 900 (did you need a parts catalog for that by the way? I've got one if you want it emailing?)

Still don't know where trav's based anyway, he could be round the corner from me yet lol

 

I have a parts diagram, but I would use a parts catalog (with prices), just to compare with Len's prices, lol!

 

lol it's not got prices on (would've been interesting to see what the parts cost back then though!) it's just the Yamaha fiche in pdf form, its got part numbers & exploded views but guess you have those anyhow?

 

I had a broken one here. Got a super welder I knew to build up a new pillar then I shaped it with a file and CAREFULLY drilled a new hole for the pin.

What I did to locate the hole was thread a straight sharp wire through the rest of the rack to make a mark for the hole. Then I drilled passed the drill bit through the good pillar and aligned it with the mark.

If you do this you have to completely strip the carburetor (including butterflies and seals) to keep the heat from ruining them.

 

Repairing a Float Pillar is sketchy.
You could have it welded.
Shipping and Labor would be close to a hundred bucks.

Buying a cheap set of Parts Carbs is the way to go.
Swap one Body or Rehab the Parts Carbs.

If you Swap the Body, ... you can sell:
• Bowls
• Diaphragm Assys
• Un-needed Bodies
• Cleaned-up or Power-coated Hats

You wind-up with less of a daunting task that might not be right.

Im from northeastern mass USA so bloke is a little far. I might need to jump on those carbs from ebay. Just a hassle becuase the bike hasnt even ran in 4 years so i dont even know what else i will need to do.
