Repairing splayed emulsion tubes
I'm not sure how necessary this is, but I wanted to find out if it was doable. The split ends of all my emulsion tubes were really splayed (maybe contributing to why they were so hard to remove from the jet towers?), and it got me wondering whether this would affect the height at which the jet then sat on top of it. Being brass (quite brittle) I figured just using pliers on them would snap the tangs, and so heated them up with a MAP-Pro torch first. It took a surprising amount of heat (a good minute) but seemed to work pretty well. Here's the before (and this wasn't a particularly bad one) -
and here's the after (it's photographed in the wrench so kind of a weird angle) -
Anyone else done this? I was careful to only heat the tangs, and only applied pressure to the tangs in order not to deform anything.

Re: Repairing splayed emulsion tubes
It's a good question. All the brass in my carbs had been absolutely whaled on by a PO to the point that it was unusable and yeah, these tangs were all really splayed too. Heating them seems to be the answer to dragging them back from the brink into serviceable shape.

Re: Repairing splayed emulsion tubes
Probably 95% of us couldn’t tell the difference, but some veteran on here recommended aligning the slots in all four carbs with the same orientation. I think it was suggested to have the open end of the slots toward the idle jet.
Apologies to whoever it was. It probably has merit towards evenly performing carburetors.
Or was that YouTube?????

Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.

Re: Repairing splayed emulsion tubes
Thanks, I'll keep that in mind when the brass I need arrives and I get to the rebuild

Re: Repairing splayed emulsion tubes
Guess I’ve been lucky as I’ve not seen that, yet ! And I’ve done a fair number of carbs over the years. The cb750f carbs that I did last fall were about as doinked up by the guy the PO paid to rebuild them as I’ve ever seen. The one carb actually had the float needle shoved through the float tang, not sure how they managed that. I seen some real doofus things done like using wood screws on the float bowls because they stripped the screw holes out, that’s a story in itself.
Also on the 750f I have, the PO paid the same guy that f’d up the carbs repair the starter sprag clutch and the guy just kept stringing the po along spending more & more money because he couldn’t get it to work. I found the brass bushing/bearing in the sprag gear nearly gone so the gear wobbled badly in & out of contact with the starter drive gear. Putz !
Anyway I’ve never heard this about lining the slots up on the emulsion tubes and would like to hear more on how this is supposed to help. I’m all ears.
Also on the replacement emulsion tubes, make sure you compare the new to the old particularly for number of holes and hole sizes, a lot of the replacements are of the Chinese kind and do differ, generally not for the better.

Re: Repairing splayed emulsion tubes
I align the slot to have a direct path to the fuel supply hole coming through from the adjacent tower. I've been told it does not matter but I believe that all the little things add up to being just a smidge better...

Re: Repairing splayed emulsion tubes
It’s as good an explanation as I have Eddie ! But being the top is relieved all around the top it shouldn’t matter, but it certainly shouldn’t hurt !

Re: Repairing splayed emulsion tubes
I thought it was you, OldFogey, but didn’t want to be wrong. Explanation is plausible and it is a minor detail to include. I had forgotten the feed hole was there for the idle jet.

Re: Repairing splayed emulsion tubes
Thanks for the link, not only to that page but also to the site in general, lots of great information there. Really love the gl1100 cut-away art too - wonder if that's available as a print somewhere?
