Seems like we're missing the vacuum tank for the '61. Can someone tell me where it was positioned and a pic of what it looked like?
Also, how does the vacuum system work, we have the centre carb vacuum valve, correct 3x2BC carbs, etc. The vacuum hose that runs from the back of the center carb seems to be missing a check valve, and now I see mentioned on other threads, a divorced vacuum tank.
As far as I can tell, the front carb vacuum can pulls the secondaries open, but does this happen when the vacuum collapses at 60% throttle? Or is there a spring in the vacuum can that is held under tension by vacuum which is then released by vacuum decrease when 60% throttle is achieved.
