Hey guys, what's a good starting point for tuning an Amal 930 carb? I've tried to mess with it but I've never really dealt with carbs before. The shop manual says 2.5 turns from closed for the pilot screw, but that doesn't seem to work. Also, what's a good starting position for the throttle stop? What's rpm is ideal for idle? Also, when tuning the carb, do you just lean it out until it sounds like its running poorly then back a little to where it runs strong? I'm at a higher altitude (~4500ft) so I heard the higher altitude makes carbs run rich. The bike is a '70 TR6R. Thanks.
