Thats called a 4-corner idle system, and its common on double pumper 
Holleys as well as all Demon carbs. Valiuable aids are the paperback book "How to 
Tune and Win with Demon Carburetion by Ray Bohacs (ISBN 1-884089-56-9) 
published by SA Design ($18.95), You can also contact Don Gould at <
www.4secondsflat.com>. Don is a Demon specialist who publishes a 10-pg tuning guide for 
only $10, answers questions even if you didn't buy from him and stocks Demon 
parts. Cheers- J DeRyke
