All - the triple SU HS6 carb setup is no more difficult to run than twins. As with the B18/20 you must have the engine in good working order before finalizing carb settings. The linkage must activate each carb identically (including the idle speed screw) and the choke setup must be uniform and not affect carb running with choke "OFF". Start with 12 flats from full lean and two turns of the idle screw then make adjustments on a fully warmed but not hot idling engine. Make four-flat changes to each carb (start with richer) without touching the idle screws and note any rpm changes and/or stumbling. If the rpm gets too low with no stumble up each idle screw one turn. Once the engine begins to lose rpm and/or stumble lean the jets two-flats-at-a-time until the idle begins to smooth out. Adjust all idle screws exactly the same until the engine settles into warm idle at about 1,000rpm. Remember to "blip" the throttle after each adjustment as this should negate any pre-tensioned changes in the setup. Drive the car checking for pinging, stumble, stalling, overheating, bucking, etc. If all is well re-adjust the idle screws and set the choke linkage for warm or cold weather as applicable. This setup will result in a "rich" mixture. For those desiring a leaner setting repeat the process but turn two flats toward lean until the idle stumbles then back two flats toward rich. This setup will need more choke in cold weather and will require the choke to be partially "ON" until the engine warms fully. None of this will work if the timing is off, spark is faulty, valves mis-adjusted, etc. or one or more carbs is faulty. On the B30 with all-steel timing gears one of the most common booboos is installing the gears with the marks one tooth off.
Go for it, y'all!
