[TR] vacum advance

[Gary Nafziger]

The lister that mentioned vacum advance reminded me of my issue with my tr-3. 
Is a functioning vacum (ok ok i can't spell for sh--)lol  advance essential? 
I have a functioning unit on my distributor but have switched carbs so that my
carb that's plumbed for the advance is the rear carb and I'm not sure the pipe
will reach.  (maybe a person could drill out the front carb to accept the
pipe?)

Just wondering.
