Changed spark plugs

The carb sync uses the same vacuum port as the advance, so by default the vacuum advance is disconnected.

Blip test, idle mixture screws, leaving it connected makes no difference.

I got a chance to go through the sync and mixture screw adjustment today. I think it takes some time to get good at it. I managed and felt more confident at the end.
I started off by rigging the fuel bladder. Your idea of using a small engine fuel tank was right inline with what I have at hand.



I drilled and wood screwed the tank on the dowel and slipped the little hose inside the big hose. It sealed up good. never seen a drop of fuel escape.
Looks like a potential streetfighter mod.

I set the mixture screws at 2 turns and took off the TCI hose.
Balanced 1 to 2 and then 3 to 4 and then 3 to 2. I did some blips and fiddled around with the mix screws but it still sounded wrong.
I plugged the TCI back into the #1 port and set up my mano on 2 and 3. It ran instantly better without turning a screw.
I adj. 2 to 3 then switched and did 1 to 3 and then 3 to 4. It sounded 10 times better then.
I did the blip and it was dropping below so I turned out a whole turn to 3 and the blip hung up. I got it at 2 1/2 and the blip is good.

I need more practice but I'll get it. Thanks for all the help. Didn't drive it today, I got a back pain and I'm kinda resting it.
I will let you all know.

Sounds like you are using a home built 2 channel manometer...if so don't leave those unused vacuum ports open while your balancing the other two..... and while performing the blip test.
#1 port should go to your petcock and #2 should go to your advance.

Ya! No, I wouldn't leave any open ports. I made a couple of extra plugs, REmoving those factory plugs as little as possible.
No harm in moving the TCI over to #1 though. I wanted to do the sync the same way I did it the first time 1-2 3-4 then 2-3 but I'd have to re-route the TCI hose to make it to 3.
The engine ran different with the TCI plugged in so I re-sync'd them. It must have something to do with timing, I guess.
