Reinstalling carbs

1) I have two hoses I can't find where they go to. One comes from between # 1 & 2 and the other from between 3 & 4. The tip look a little stretched out so I assume they need to go somewhere. The both come out facing the rear of the bike. The aren't my overflow tubes because the 4 tubes weren't there when I took everything out in the first place.
2) Carbs 1 & 4 are connected by a T tube and go to the front of the bike (not the issue). Carb 3 runs a vacuum tube to the petcock while carb 2 has a couple inches in length of tube with a screw in the end to close it off. Should 2 & 3 be connected by a T as in 1 & 4 and then running to the petcock? Or doesn't really matter the one tube should do just fine?
Thank for the help

2....1&4 vacuum fittings are connected by small ID hose to a tee fitting. Out of the tee fitting another hose runs to your emissions vacuum switch. If you have the emissions stuff on your bike, these hoses MUST not have any leaks or holes. Either #2 or #3 carb vacuum fitting is connected to the petcock and the other carb's vacuum fitting MUST have a vacuum cap on the vacuum fitting.

I was able to finally get the engine to start but it sounds like I'm on the line at a drag strip, very high speed idle.
I checked the throttle cable and that moves cleanly and returns to position. Rechecked all the hoses and boots are in place. Not sure what else to check.
I guess too much to hope I could get them in and out my first time without issues.

Had exactly the same problem earlier this week after helping a friend (also a board member) change the throttle cable on a 750LTD - he didn't get the carbs back properly! Loosened clamps, pushed/wiggled 'em in place, tightened clamps and bingo!
P.S. - Does anybody know of an easier way to change the throttle cable on an '81 750LTD. Seems damn near impossible without taking the carbs off! What a PITA!

Same thing on the 81 1000LTD. I forgot to connect the cable before installing the carbs once and it was a royal PITA to do but I finally made it. Replaced the cable this spring and another set of hands to hold the carb linkage in the full open position while I connected the cable was a little easier but still not something I'd want to do again.

The boots on both sides of the carbs seem to be in as far as they can go. Would the WD40 on each boot work? I'm just afraid of winding the engine up even higher without a load on it.
It's probably shop bound if I can't figure this out soon. Thanks

The bike will now start but just at a very high idle. The following is what I've done or found
1) I forgot to tighten the clamps on the front boots - now nice and tight and the boots are well seated both front (carb to engine) and rear (airbox to carbs).
2) Rerouted fuel line so it's not going between # 2 & 3 carbs
3) Backed off idle screw (large thumb screw on back of carbs) - no real noticeable change when starting bike.
4) Just in trying things I ran it without the tank on since there was gas in the carbs and if I put my finger over the vacuum tube that would go to the petcock that would change the increase the idle speed.
Not sure what to check next. Throttle does work just increasing the speed even higher.
