any Ideas what's wrong with my sync?

[cowboyup3371]

Castlekin, listen to these guys and stop everything else first. When you say you looked at the orings, what do you mean? Were they supple and in one piece or were they hard and brittle? What about the boots? Was the clearance within specs?

When you are completely ready to do the sync, read what Steve says. The number 3 cylinder will be your baseline. Loosen the locknut and adjust the screw between 2 and 3 first. Tighten that one back up and then move to number 1. Repeat. Do number 4. Make sure your temp tank has plenty of fuel and throw a fan at the front of the bike to ensure every thing stays cool.

Trying to find some other shortcut around this is going to mess you up even further. So, do what is recommended and you'll be on the road in no time.

My homemade Manometer is this thing. The first pic is about an Hour after I tried to sync the carbs the first time.



And this is after I ran the bike for a few minutes after taking the first Manometer pic.



See how number four lost some fluid? Note: the carb bottles are inline with the carbs when looking from the back of the Bike

Cowboy, the O-rings were nice and soft and the valves and cams were within specs( that's what I was checking them for).

I do want to thank you guys for answering, can't wait to hear more and update you guys on it.

Do you have restricters in the lines?

[castlekin]

no I don't. What would you suggest?

Just to let you know that once I got it comer than it was in the beginning all that air flowing through the lines stopped. Now the fluid moves through the lines in between the bottles without any air.

Just how would that happen?

There is no connection between 3 and 4 that would allow fluid transfer, except the fuel inlet from the tank.

.

was thinking he was using a different manometer "tube style" the manometer is the connection between 1 and 2 , 3 and 4 if you have a positive vacuum on one side and no vacuum on the other it will suck fluid into combustion chamber

[castlekin]

Also, correct me if I am wrong, turning the mixture screws counter-clockwise lowers the pressure in the engine( closes the butterflies?), and turning the mixture screw clockwise increases the pressure.

[Big T]

no I don't. What would you suggest?

The ones that come with a Morgan Carbtune

How are you connecting the tubes to the sync ports?

[castlekin]

using 3/16" brake line cut in 2.5 in lengths and the threaded.

No, turning the mixture screws does NOTHING to adjust the "pressure" in the engine.

You have to use the SYNC ADJUSTERS.

Sorry, but I have detailed it THREE TIMES for you and even given you a picture from the factory manual.

If that is not plain enough to tell you what to turn and in which order, I'm outta here.

I do appreciate it when people have enough sense to ask questions,
but when it's answered MANY TIMES and ignored, I refuse to go any farther.

Steve I get it, and I gotta say, you have been informative. I am not arguing with you on any of this info at all.

I am just trying to wrap my head around forum text( I am a more hands on and personal instruction kinda guy). It sometimes takes me a while to get text.

I don't have any time to work on it this week, as I gotta work til Monday. I am going to start again on Tuesday, using your instructions. I think I got it, Steve, and I wanna thank you.

Also, what do you think of the Homemade Manometer?

[castlekin]

Oh, and Steve,I gotta say because of how forums sometimes work, when I was writing again, you were posting( just looking a again over previous communications between us).

Also, what do you think of the Homemade Manometer?

In a word?

SCARY.

I am not understanding how all the tubing comes into play with all the bottles and everything, so I can not form a good opinion, but from what I see, it might be highly suspect. Would have to see it in person and in operation to understand it.

Please pardon my newbie ignorance but what does time have to do with it? "An hour after I tried to sync the carbs".
If I took a picture of my gauge two seconds after trying to sync my carbs, it would look the same as two minutes, two hours or two days after trying to sync the carbs. Please explain the significance of the "hour after".

And this is after I ran the bike for a few minutes after taking the first Manometer pic.

Does it really take you a few minutes to show a difference in vacuum levels?
If you were to make an adjustment, how long would it take before you can get a reliable reading?

How long do you think it would take you to make the adjustments? I mean, from the time the bottles are prepared, the hoses connected and the bike is ready to fire up, until you are satisfied that is as close as you are going to get it and stop the engine?

Just curious how that compares with a two-minute average in my garage.

See how number four lost some fluid?

Where did it go?

I watched the video. I must be missing something, because I did not see any changes. I heard the engine running and I saw different levels of fluid in the bottles, but have no idea what that means. As mentioned in previous post, I would have to see the entire setup in operation to understand it.

was thinking he was using a different manometer "tube style" the manometer is the connection between 1 and 2 , 3 and 4 if you have a positive vacuum on one side and no vacuum on the other it will suck fluid into combustion chamber

Not understanding this, either. With my mercury gauge set, I can connect any number of vacuum hoses to it without sucking mercury through the engine.

Also, correct me if I am wrong, turning the mixture screws counter-clockwise lowers the pressure in the engine( closes the butterflies?), and turning the mixture screw clockwise increases the pressure.

Be carefull with your terminology. You are measuring VACUUM when you sync. Vacuum is the absence of pressure, so "increasing pressure" is really lowering the vacuum level.

Steve I get it, and I gotta say, you have been informative. I am not arguing with you on any of this info at all.

He told you what to do, you said you did something else, he told you again, you said something else, he told you a THIRD time, you said something different. That's not arguing?
