break on belt drive

[babycakes]

Has anyone put a break on the belt drive in order to make shifting easier? I was thinking about using a old break system from a snowmobile, but I thought I would ask if there is an easier solution? Right now I give it a little blip to slow the idle down, but there are times when its a pain! I don't why you have to give it a blip to slow the idle down in the first place, but for a lot of argo's it seems to be normal.
Thanks guys!

I have heard of people wanting to do that but cant remember anybody doing it. You can also pull the choke to get the idle down some.
