Carb Syncronization Question

[texasengr]

It has been a long time since my last post, but the bike has been out of commission and I have been involved with other things.  I hope some of my old friends are still active on the board, but I would appreciate any help with the below.

As I said, the bike has been out of commission for about 6 months with very little upkeep.  (I know, please spare the lectures.....believe me I am paying for it.)  Consequently, I had to drain the gas tank (10% ethanol gas SUCKS) and clean the carbs.  I took the opportunity to replace the jets and the carb gaskets with new ones.  Everything went together well and I got the bike started and let it warm up so I could sync the carbs.
I got the two vacuum gauges hooked up and restarted the bike setting the idle around 1750 rpm (according to the onboard tach).  The left cylinder is pulling 15 cm of Hg and the right is pulling 45 cm of Hg!  According to the Clymer, both gauges should read the same so I began adjusting the throttle screw between the two carbs.  This is the screw with a spring on it that attaches to the idle adjuster.  As I adjusted this screw both vacuum gauges increased and decreased by the same amount.  The Clymer tells you to adjust this screw until both carbs are pulling the same vacuum and hence the carbs are syncronized.

Does anyone have any tips on what to do to pull the same vacuum on each carb?  Does this really prevent one cylinder from trying to 'run away'?  Anyhow, thanks in advance to anyone who can help!

I guess I don't any more.

The only other thing to do is to make sure both floats are at the same level.  Use the "clear tube method".  After those are at the same level you should be able to get vacuum synchronized all the way to redline.

Thanks, but what is the clear tube method for float height adjustment?  I tried to measure them on the bech, and got them as close to the same as I could - but obviously didn't get them equal.

I appreciate your help scratch.

Clear tube method: Using a clear tube, attach it to one of the drain spigots under the carb bowls, route the tube up alongside the carb, open the drain screw and watch where the level stops (should be no more than 2mm above the bowl gasket level).  Repeat for other side.
