Holley Adjust-a-jet?

[CobraSix]

Was looking through one of my performance part catalogs and ran across the Holley Adjust-a-jet kit metering plate. You place it in between the Metering block and the fuel bowl, and you are supposedly able to adjust the main jet with the turn of a screw.

Here is the part: http://www.holley.com/HiOctn/ProdLine/P ... 55001.html

Anyone using this? Is this a good idea? Just curious. It seems a better way to be able to turn a Holley carb without constantly changing the gaskets out to get to a the main jets. You can also tune the main jets with the car running.

Any inputs would be great, especially if you have this system.

I read several past articles on this device. It used to be made by a fellow named Percy and was called the Percy Adjust-a-jet. Holley thought it was good enough to buy, so they got the rights to it and now market the kit themselves.

It is supposedly a pretty good way to tune the main jets.
