On the 82 gl1100 if you are sitting on the bike the vacuum line goes on the right side closest carb to the seat.under rubber manifold intake.

Kinda hard to see. It's on the very back of the engine. Infront of the swing arm

Yes, that line goes to the vacuum advance at the back of the engine. If it is not hooked up, your engine will not run well.

It connects to the pulse generator, mounted on the back of the engine (shown here with the cover removed):

The vacuum line from the carb plugs into the pulse generator where shown by the red arrow:

sorry I miss read the 1100 engine in a 76 frame thought you had 1100 carbs on a 76 engine..then you plug that line as 1000 engine had no vacuum advance..my mistake.

The line on the carb is deffinately for vacuum advance. The second pic in your last post ahows what looks like a stub of vacuum line. If it is I'm sure that is where it would go. If the pic is of the right rear of the engine, as your sitting on the bike

Whatever you have there looks strange to me, It simply doesn't look right, I don't see the canister in this photo, looks like someone did something odd too it..There should be a canister as shown above in the diagram...Can you take a few more photo's...Something ain't right about that...it almost looks like the fella that sold you this bike pulled a fast one on you, it looks like the whole back of the pulse generator is gone and he put a fake cap on the rear somehow to get the bike sold..I think I just figured out your issue...The 76 frame that you have will not have the clearance of the 80,81,82,83 frame...Guess what? your gonna need to just plug the hose pipe at the carb and not have any vacuum advance, it's not that noticable according to a professional mechanic or Randakk's guy Howard ..The original fella that tried putting this engine in found out it wouldn't go on and rigged up a cover for where the canister should be no way it can function without it...Sorry man...Bike will still run good without it... :D Listen up, I could be wrong, maybe there is clearance I'm assuming there's not...the reason behind my thoughts is because the 76 didn't have the pulse generator on it, I think it has the points system..

Well, here's the site where Randakk's guy says to plug the carb http://www.randakks.com/TechTip71.htm Now keep in mind he is saying this because the diaphragm in the canister is bad..he's still getting the spark signal thru the plugin wires I think just not the vacuum advance, your vacuum advance is gone, I have a question is there still a wire and plugin that goes to the unit as shown in Wingadmin. photo above? Here's the thing having the vacuum advance there does this, there's a control arm that goes into the canister when vacuum is on, that arm and the position of that arm is factory set for the timing, it moves the base plate and pickup coils inside there when vaccum is applied... What's funny to me is why did he put the hose there like that unless he cut it off the canister top and fitted it there...Funny guy...really the only opinion I see is to get another frame. or just plug the carb but who know's where your timing is at...I'm making timing caps so guy's can see there marks on the crank with a timing light for like 10 dollars.

Oh there's one other thing, how much fuel in in the tank...just the other day My bike would die after I pushed the choke in and it would just die and everytime I gave it throttle it would die out, hummm this has never happened to me, I finally realized my fuel gauge showed just near the low point so I moved the petcock valve so it was pointing down in the reserve position and guess what... everything went back to normal..Check fuel delivery as well..
