Carb syncing question Options

[Cevan]

I'm trying to sync the carbs (Weber IDFs) on my new engine. I warmed it up and then let it idle at about 800 rpms. I disconnected the linkage and used the synchometer. On one carb, both barrels were very close to each other (5 and almost 5), while the other carb read a 5 and a 3. Is this indicative of a bent shaft or some other problem, or can this be adjusted?

I do recall removing the throttle plates from one of the carbs while I was cleaning them. I was going to remove the shaft but decided against it and put the plates back on. Might I have changed the position of one or both of the throttle plates in relation to the bore? Would this cause the problem?

Also, fuel seems to be almost weeping in the area of the brass bolt and washer (#5 and 6 in the picture) directly under where the feed line connects to the carb. I used a new washer and tightened the bolt real good. Any ideas?
