So ...need a bit of direction-was carbs, not coil pick up

[JonnyO]

So you guys will laugh...
Got the carbs back on and the tank and fuel lines all buttoned up and turned it to prime and it started right up. Wow. SWEET! ( or so I thought. ) I went around and was putting the side covers and seat back on it and looked and saw fuel dripping!!! From the carbs. So I thought anyway. In my head I'm screaming NOOOOOOOO!!!! All that for nothing!
I turned off the fuel and then looked CLOSELY and determined the fuel was dripping down from a hastily attached fuel line to the T on the right side. Lmao. I told you guys I suck at mechanically inclined stuff.
Anyway I cleaned that all up and reexamined the other side too and pushed them all on a little farther and buttoned up the air box and left the air filter section off and rode it for a mile and parked it in the garage.
I plan to ride it to ping pong at the Rec Center in the morning as it's first real test ride of a few miles.
I know there's a lot more I SHOULD DO to the carbs but I don't feel qualified to do it. You guys point out parts and things to do and I have NO IDEA what you refer to. I just wanted to start by addressing the immediate problem. The bogging and fuel leaking into the air box. BikerPhil's use of the part# and the correct carb diagram on Partzilla gave me my first clue TO WHAT THE HELL I WAS TRYING TO DO. I don't know a needle jet from a hole in my head.
Now I KNOW I can get them off and reinstall them. Even tweak 'em a bit. I expect something else will go wrong but you guys have given me a bit of hope that I might be able to repair it myself. I'm no LAB3 or the guy in Holland who fabricates his own parts and built that bad-ass turbo, of that I've no doubt. I figure I've earned my yellow belt in Ya Ma HA. lol
Thanks. I'll let you know if I'm crying like a little school girl if she runs poorly tomorrow.

Good luck with the bike. Hope it runs well enough for you to enjoy it. I edited my post and your copy of my post when you replied so that folks reading this post won't be misinformed. It was concerning the emulsion tube removal. Fixed now.

[JonnyO]

Thanks Cajun. So uh what is the emulsion tube? I don't see it listed on the carb parts diagram. I'll try google.. The needle jet?

[Schming]

The needle jet screws into the emulsion tube from the float chamber side/bottom of the carb. The main jet/needle jet holds the emulsion tube in place. using a proper sized wood or plastic dowel the emulsion tube can be tapped upwards into the venturi and out so it can be cleaned. There are small holes on the sides that have to be clear to achieve proper emulsion of the fuel and air.

[cajun31]

Thanks Cajun. So uh what is the emulsion tube? I don't see it listed on the carb parts diagram. I'll try google.. The needle jet?

In the carburetor schematic it is referred to as the nozzle main. it is item 52 in the Partzilla link I posted earlier. The main jet screws into it. There is a washer underneath the main jet. As Shming stated once you remove the main jet and washer a wood dowel of the proper size can be used to tap the tube out or as I suggested a float bowl screw can be used. If you just screw it in just enough to get a good bite enough of the screw protrudes above that gives you enough room to get the tube moving down by lightly tapping on the screw. A wood dowel is a safer bet from start to finish. The varnish that builds up, and for sure has in your carbs from the condition of the other parts you posted pictures of, can make it more difficult to remove and can also block the holes in the tube. The reason I said soak the carbs in Berryman's before disassembling. My concerns are that without a thorough cleaning from this point forward you are never going to really get the carbs to perform properly. You will fight problems from here on out. At least at this point when you suffer performance issues you will know that the problems are probably the carbs.

I might add that there have been numerous discussions on what purpose those holes in the tube serve. They are sold today with holes and without holes and both seem to work. We say clean them because, obviously clean is better and allows the flow of fuel air much better.

Well.. Who let the wind out of my sails!
I guess it was appropriate that one of the guys playing ping pong was wearing a Doobie Brothers T-shirt.
"Get back, Jack, do it again"
Desk person comes in and says who owns the MC? Posse says it's leaking something.
lmao. Made it home with the throttle all the way out. Didn't bog as bad as before. So there's that.

'm going to look at it close; when I get the gumption to start again.
lmao ( well at least I didn't cry or get angry. I'm still happy I got it back together.
So I guess it's the berrymen's treatment and complete rebuild.
Can anybody give me a link to gen part rebuild kit?
I'm presuming, Cajun, that a complete tear down and rebuild is what you suggest because of what you suspect is in the emulsion tubes? Start with a soak in berrymen's right?

It's safe to look now??? (O_o)

Actually, nope. More to be done. *sigh*

That is what we have all really been saying. Here is a maintenance tip that helps to get you going in the right direction. Carb Cleaning 101 - XS11.club Forums. There are also videos available out on youtube that help.

One thing I don't recall being mentioned was the condition of the rubber coated fuel T's between carbs 1+2 and 3+4, it should be visible from the outside/between the carbs if leaking.

Another thing is maybe remove the carbs, take the air box out and set aside, then reinstall the carbs, then you can pinpoint which carb(s) is leaking.

Bikerphil, are the carb fuel T’s between older (79/80) models interchangeable with the newer (80/81) models?

The parts numbers are different ( 3H3 1498800 vs 2H7 1498800, I presume because the earlier are Mark 11 and later models Mark 111?). And the earlier Tees are shorter than the later ones going by previous posts.

This topic has been discussed in earlier posts, best one ‘Carb Tee repairs’’ , thanks guys 💪 but I’m still unclear on this. There’s a place Sirius Consolidated Inc that makes aftermarket Tees for the early carbs. Will these fit my ‘81 carbs?

FWIW... Sirius Consolidated wuz where I bought the Tees fOaR my Test bank AND the bank installed on my bike. (^_^)

For my needs, on my 79 special (3H3...), the LONG Tees from Sirius were a poifect replacement fOaR the Fuel Tees and the SHORT Tees were a poifect fit fOaR the Vent Tees. (O_O)

Seems that on my 79, the OEM Vent Tees frum the factory were way shorter than the OEM fuel Tees. I just went with getting long fuel Tees and short Vent Tees cuz that's the way I found things. (◕‿◕)

Hopefully, Bikerphil can chime in and confirm that the Long Tees are wut you need AND that the 80/81 carbs don't even NEED vent tees cuz they have an extra hole in the intake horn just fOaR that purpose... (O_o)

Thanks Larry! Yup, my carbs don’t have vent tees. I’m hoping the fuel tees are the same but I haven’t ordered yet because it appears the parts numbers for early and late model fuel tees are different. And while I have the carbs off the bike…

Im reading about your upcoming bike rallies, it’s a dream of mine to tour the States on a bike some day. Ho hum, one day I guess

Larrym, looking back I found this post which dealt partially with the fuel tees and interchangeability.
