Carb sync help
I'm no expert but I think I finally have the carbs synced. You will need the tee to connect everything and its imperative that no leaks exist in the temporary connections. Once connected, suck on the line that would normally go to the carb. When you have vacuum close the opening with your tongue to seal it and watch the vacuum gauge to make sure vacuum holds. Also, you will need what I consider to be a regulator to smooth out the fluctuations in the gauges. Start the engine and open the regulators and the gauges will be wildly fluctuating. Slowly close the regulators so that you get steady readings on both gauges. As far as the adjustment, yes the screw is a real pain to access. What I did was to note the reading for the rear carb (that's the one you're adjusting), stop the engine and open the throttle so that the screw can be reached. Turn a half round or so (clockwise increases rear carb vacuum and vice versa) and start the engine and see where that got you. I did that several times and got the carbs synced.
Good luck with it!
