    Well, they do lift the carb off the intake, thus allowing the carb to run cooler. Also, its advertised that the higher position of the carb creates a ramming effect of the fuel, and allows it to mix more thoroughly. I've got one on my Sub...it seems to have a little bit more power...but without a dyno, I dunno!

    Pretty much a slide in deal...with the exception of the choke problem that you mentioned. I have electric choke, so mine was a simple 10 minute job.

    I had one on my old '77 K5 in high school. It seemed to help, but only at the high RPMs. The down side was that it made it a real pain to start in the winter time. Don't know if it was just an individual problem to my K5, but I took it off because of that.

    Mud is just thick water, or is it that water is just thin mud?

    I broke my choke rod trying to bend it one time and couldn't find a replacement, so i took a welding rod, striped all the junk off it and bent a new one, a little epoxy on the end to keep it in place, perfect. thats how i solved the choke problem.

    The spacer is used to make more power at higher RPM's by letting the fuel/air mix better and cooler. I had a 2 inch spacer on my 71 Monte that I drag raced. I was going to put it on the blazer but I don't need to wind up the motor that often.

    A carb spacer will help your low end if it is a 4 hole spacer. If it is a single plane spacer (1 big hole) it will hurt low end and help high end power.

    I was told by a very reputable carb builder that a carb sapcer on a low RPM application wouldn't do anything. They are good for high RPMs.
