So was doing a carb sync tonight using the ol' 'ear method' and a few questions came to mind.
1. What is a good base setting to start with, for the idle stop / speed screw?
I want to be sure I start with the same or nearly same adjustments on each side
2. I noticed that at some point, one carburetor would seem to be "in charge" or "taking over". Only way I can describe this is that at one point i noticed one cylinder would seem to be trumping the other. I would adjust the idle speed / stop screw in and out for a ways and very little change would happen. Also when adjusting the idle mix screw on that same carburetor, it would not seem to change the engine rpm at all. I noticed this happen specifically on both sides, on different occasions. Once I adjusted the "in charge" carb down slightly, the other carb would seem to once again be able to be adjusted.
What causes this phenomenon and is it normal?
