I'm also in my 50s and been doing this for a very, very very long time.

If you read my write-up, and understand the true meaning of Carb sync then bench sync is the only true way to go. As I've stated in my write-up too many other factors come into play when doing the vacuum method.

Is funny that people blame the Carb sync for a problem that just popped up, odds are it's something else, valve adjustment, float adjusted properly, spark plugs caps, HT leads, have the idle mixture screws been dialed in, etc..... You see where I'm going with this..... A, sudden change in performance isn't a sync issue

Too many times I've seen it go horribly wrong, and cause people to chase a problem that they themselves has caused, and the problem won't go away due to the damage has been done, so to speak, and not corrected.
