over Single Holley AED Demon QFT or Edelbrock Carb Benefits of a Carb the Looks of Injection most radical motors in racing are 'injected', but because real constant flow injectors are not designed for part throttle operation, most rodders because of costs or technical and drivability difficulties either have to go to an expensive efi (electronic fuel injection) limited to a 4bbl carburetor and aftermarket intake manifold. left the serious owner of a four barrel engine with no authentic alternative intake look other than an air cleaner or blower typeThe 'wild injected look' without the associated problems and costs of running a real injector and now with larger 2 9/16" tubes and Ram Tops giving a fuller look so the choices are all yours (the pictures on this page are 2 1/2" tubes). unmatched in quality the IN600 Street Induction is directed toward of a four barrel engine while at the same time wishing to pursue a relatively inexpensive method of providing a full race look to

full use of this Carb upgrade a few pieces of info on demon carbs and the ultimate chart... what all the demons are built with.. this model also comes with the IDLE EZ circuit.. its hidden under the air cleaner stud.. this allows the idle speed to be controlled without uncovering the idle transition slots in the base plate. if anybody has adjusted the idle speed setting screw on the base plate.. it needs to be backed out and the EZ idle screw under the air cleaner stud needs to be backed out to restore bypass air.. so that any fuel at idle is coming only thru the round idle feed passages instead out out of the idle transition slots.. The Following 2 Users Say Thank You to waynep712 For This Useful Post: eric32 (05-24-2016), RWENUTS (05-23-2016) Easier than a long explanation. There are several more on youtube like it. The Following User Says Thank You to eric32 For This Useful Post: the biggest issue of carb tuning is realizing that there is an entire circuit that is missing in the instructions..

the Idle Transition Circuit is actually the LOW speed circuit.. and supplies the engine with fuel from idle thru 2400 RPMs give or take.. it is the sole supplier of fuel from above idle to around 2000 RPMs.. depending on displacement and carb size.. this is what will make or brake off idle part throttle acceleration.. and it will effect cruise fuel economy and driveability. i personally don't like screwing with the idle air bleeds.. but i do make huge differences in enlarging the idle feed restriction. .002 at a time.. if it needs more take it off and take out another 0.002" .. you don't want to go too big.. as that will effect fuel economy.. if you are too small.. it gives you a lean hesitation off idle.. i would like the Original Poster of this thread.. to open up the EZ IDLE screw under the air cleaner stud.. then close down the idle stop screws that control the linkage closed position. this allows the slightly adjustable to get the carb perfect exposure of the idle transition slot..

different engines require a slightly different adjustment.. of both the idle speed screw and the EZ IDLE screw.. at least with that demon version. the IDLE FEED RESTRICTIONS are already easily changeable. it only takes time and money to purchase the various sizes and change them out. Originally Posted by eric32 replacement idle feed restrictions are actually available from walker products and the people who sell their stuff. page 21...and page 24... 85-607 idle channel restrictor replacement press in air bleeds are next to it... 85-608 and 85-610 depending on the vintage of the carb.when you go in the parts store and buy an aftermarket brand carb kit.. it will have walker part numbers on the end of the internal box most of the time.
