so i was attempting to fix a vacuum leak and i was snugging up the bolts on my carburetor when i heard *crack*. ah ****, i tightened it too much.

now im probably going to try and throw some JB weld on it just for ***** and giggles cause there isnt much else i can do with a broken weber.

so my question is. who thinks it will work, and who doesnt, and why. is the crack near and important vacuum source or signal?

here are the pics

 

That SUCKS!
How much effort do you want to put into her? I think you could have a bead put on the outside of that, but I would only have a qualified, experienced, old man of a welder do it.
On the cheap side, I think if you're really careful with her, you can mount it and seal it from the outside. It shouldn't leak, but if it gets tweaked, it'll just get worse. It may even get worse just from the vibration. Use a fuel-proof sealant. JB weld is great for sealing substantial leaks, ports & crevaces, but fuel does get between the metal and the epoxy. Eventually it will peel off.

 

Sterling, fuel wont touch that area right (I do not kknow carbs, your the x pert)

Anyways yeah do it man, ****** seal it up some how after doing it and see if it leaks if not throw it on the engine and see how it runs haha

 

dude its trash....just save some space and send it to me ;(

 

Duct tape.....

 

I dropped a mikuni by accident. had similar crack like yours. Rob @ Rotaryshack brought it to one of his boys who tig-welded it. so hit him up. be sure to take it apart and just send him the casing.

 

i don't know much about webbers but that looked like the bottom end of it, so it might get gas, even if it doesn't directly get gas, it still gets some very strong gas fumes

 

i've not had the best experiences with him.

 

This is the only correct way to get this fixed. You don't have to go through Robert, but you'd beter find someone who really knows what the hell they're doing or you risk getting a $400 paperweight back. Go with Robert...

 

Send it to RotaryShack.

 

i'm sure they will treat you right this time, send it to them and everything should be peachy

 

Well, I can give you one dollah for your paperweight.

 

 

If you could use it in the ports, wouldn't it work for the carb. The ports get fuel also. I agree having an experienced tig welder do it for you.

If your going to use a jb weld or similar, Be sure to take a dremel tool and back-gouge the crack both sides at least 1/16" clean the area with some acetone (fingernail polish remover). Actually If your going to have it welded do this also and it will save you a few bucks. I don't have any access to a tig welder or I'd give you a hand.

 

Sending it to rob would probably be your best bet.I Have been dealing with him since i started my 12at project and hes been nothing but help altho at times it can take a while to get ahold of him.

 

well he still has my other carb...

 

I did the same damn thing with my weber carb only on the other end with the bolt that holds in the venturi. I JB welded it on the outside and left the inside alone. I figured that it wouldn't really be an issue in my instance because the venturi, the auxillary venturi, and the velocity stacks all slide in there so that the crack isn't even really exposed. With yours being on the other side right at the butterfly an air leak would be more of a concern.

Good luck man!

 

Have you used the carb with the repair yet? If so, how long? We need to know how the JB weld's holding up? that would solve his question of to do it himself or not. But in perfect circles case I would recomend the whole crack be ground out. With JB weld he'll be able to smear it into the crack and use somthing to smooth it to where he won't need much grinding down if any.

Also be patient and don't buy JB Quik. **** hardens way to fast. and is crap for any long lasting repairs. IMO

 

Prolly only have 500 miles on since the repair. Its working fine but in its infant stages

 

You need to have that thing welded. With just JB weld you'll never be able to properly torque the carb down. When you try to it will twist and crack again...

 

I agree with everyone with welding.

 

What's the deal with your other carb? Can't you get that back from Rotaryshack?

 

His other carb is in pieces and never worked. There was a confusion between them in regards to "free labor" but the old carb is in a box ready to be sent back.

 

does that include the bonnet that i sent with it?

oh and did you get that pm about the spoiler?

 

Whatever you sent will be sent back I guarantee that. I did get the PM, very interested but gotta wait for the next pay check. I'll make you an offer tonight on that.
