82 XJ Maxim Vacuum Hose

jb weld, drill and pin it. there is no tension on it. let it cure a few days before you put gas in it.

 

Ryengoth thank you for the suggestion. I’ve got jb weld but I think I may be better off taking it to a machine shop to have it drill and pinned... maybe

 

Forget about fixing it.......buy a used carb body......someone from this forum will have an extra one.

Trust me.......trying to fix it is a temp band aid if it works....

 

Hopefully the 650 is more prevelent because I am still looking for a carb body for my 550, with no luck. Post back if you find something.

 

Using JB weld is temporary.
Having it fixed properly by a machinist or someone who is good with a TIG is permanant.
But then, that can cost as much as buying a spare rack to rebuild unless you have a freind that works for cheap.

 

That thin old casting would be very difficult to TIG weld, thus why I suggested pin and solvent resistant epoxy. Apart from that you find a replacement.

 

Heck, send it my way and I will try to TIG tack it back together for the video footage if you plan on tossing it. No promises as it could just go poof into a blob. I can return it, success or not. lol

 

There is at lest one fella who does that work. He does such work as a hobby though, so we don't try to send him any business.
Polock cut a dovetail and pinned his.
I've left the rough break for fit, and toe-pinned one with press-fit pins (tedious but effective).
Cutting the break flush and drilling for a small stud, and making a replacement out of round stock is also an option.
Many, many ways to fix that sort of thing if you have the time and patience, but if you have to pay someone it's usually not worth the cost.

 

Thank you everyone for the recommendations and input. It’s very helpful

I’ll call around town and see if anyone could cut in and pin it for me for a decent price. I’ll probably search for an individual carb body as well.

 

Can anyone tell me whether or not carburetor #2 and carburetor #3 are the same?

This break happened on the inside right carb (#3), but I am seeing some inside left ones (#2) on eBay. Not sure if I can buy that and make it work as a replacement.

 

IMHO it's best to leave the rough break and center pin it since machining out material, without replacing it, will cause the float to sit uneven. Try setting a float level with it crooked. You could also use a small metric press-fit nutsert (m3 or m4) in the body and thread a stud into the broken off piece as a quick-fix as long as the break is fairly level. For stuff like this, like you said, there's a ton of ways to fix it if you know how to.

 

YES-- body 2 and body 3 are the same. T-shaft assemblies are different. The same body is used on the 81-83 xj750's body #2/#3, as well.

Little update for y’all. Bought a new carb body off of eBay. I am currently waiting on new throttle shaft seals and fuel tube o-rings from a Chacal

I think I had said earlier that one of the previous owners had put some sort of sealant outside the fuel tubes between carb 2 and 3. I got the carbs apart and there was some sealant gunk inside the carb housing and the fuel tube itself. No bueno.

Some of the o rings on the brass fuel tubes are pretty flat and roached out. They definitely were never replaced (At least recently) which explains why someone had tried to seal up the tubes with that stuff.

Does anyone have any recommendations on what to soak the brass fuel tubes in to help get that sealant gunk off? I worry that soaking in carb cleaner may be bad for the brass. Thanks!

 

Break the whole rack down, and do a complete rebuild. The cleaning fluid will help soften any thing. You can also use heat the soften stuff. If you don't do a thorough cleaning and rebuild, you're gonna go in circles

 

Rack is all apart. Carb cleaner won’t hurt those brass fuel tubes, will it?

 

Berryman wont.

 

It can make it darken in color if you leave it in too long,but the darker color mostly rubs off

 

Btw.... All apart means ALL APART.......like this-

 

Yep, like that. Taking them to church.

 

Good
