HS4 vs HIF4?

[bobj@meaddata.com (Robert Jones)]

Which is better, HS4 or HIF4 carbs on an MGB?  I picked up a parts car
over the weekend and it has HS4 carbs, whereas I currently have HIF4
carbs on my car.  Is there any compelling reason to switch?  Is it
true that HS4s are more adjustable?

Also, has the ftp site name changed from hoosier.utah.edu when I
wasn't looking?  I want to put parts from this car forsale in the
autojumble directory, but I'm getting unknown host messages when I try
to ftp.

Thanks,

Bob
