I ordered these tiny brass parts with calibrated, metered holes that can be changed out to allow the proper amount of fuel into the engine. I am happy to report that the tiny brass parts are in fact equipped with calibrated, metered holes and that they in fact will allow the proper amount of fuel into the engine when used appropriately. I suggest if you need tiny holey brass parts for your metered fuel leak, you purchase these holey brass pieces.

The Holley Jet Kit I purchased was exactly what I needed to get both my 750 and 850 double pumper's dialed in. I highly recommend purchasing a kit if you are having any kind of lean at speed problems, or the dreaded smells like bad exhaust just setting in one spot so you have to move constantly because its to rich.
