Carburetors?

Ordered the clutch discs(requires 2). Spark plugs are on order.  I'm starting to focus on the Weber carburetors as a source of my engine vibrations. The engine uses 4 carburetors. 2 for the right bank(4 cylinders) and 2 for the left bank(4 cylinders). There is a chance the carbs are not synchronized. Certain cylinders will be getting more fuel than others. This would result in uneven explosions in 4 out of 8 cylinders. I've ordered a tool that will sync the carbs.  All this stuff should be here next week.
