No, that slight bit of extra advance while crusing is something you 
can only notice if you're keeping very close track of your gas 
mileage, and even then it's hard to be sure. Many people drive with 
bad vac cans for years without knowing it.

I have both good used and NOS #265 cans in stock, as well as all the 
other '68-on Type 3 cans.

Too lean and poor gas mileage seem contradictory.

Have you check your 4 SP connectors for resistance?
