My 1275 with 1.5 SU carbs is a little slow to take more throttle.  If I use 
the choke to richen the mix a little bit under throttle it's like a 
different car.  Where do I start to get it right?  I've read before changing 
carb settings I should check other things.  I may have an issue with vacuum 
and its getting vacuum from the front side of the balance tube.  If anyone 
can help me with the order of things to do that would be great.  I've got 
all weekend to play with it.
Thanks.
