     CARBURETOR TEST GAUGE KIT 7862HP
    For Holley 0-80540-1 600CFM Carburetor

    This kit is designed to check the Holley series 600CFM carburetor. All of the test gauges are of the "NO-GO" design which means if the gauge fits into or over the item being checked, the carburetor is illegal. The kit consists of the following gauges:

    78621P Venturi Gauge - This gauge will fit around the booster from the top and should not go into the venturi. This would also be a good time to check the venturi bore to see if it has elongated of "Egg-Shaped". This condition will be easy to spot at this time, as the gauge will not go in but you can see light around the front and backside of the gauge showing the venturi has been altered. Do not question a slight
    imperfection, as a cheated up venturi will be easy to spot.

    78622 Throttle Bore Gauge - This tool should not go into any of the throttle bores.

    78624 Combined Throttle Shaft and Plate Gauge - This gauge should not go over the throttle shaft and plate combined.

    78594 Booster Length Gauge - This gauge will go into the venturi and check the height or length of the booster. If it fits over the booster has been altered.

    78595 Booster I.D. and O.D. Gauge - This gauge can be used from the top. One end will check the O.D. and the other will check the I.D. The I.D. is where some will alter to get more air by the booster. If the gauge will fit into the booster it has been altered.

    78596 Booster Bottom O.D. Checking Gauge - Turn the carburetor upside down and open the throttles. You will now have room to insert the gauge at an angle to check the booster outside diameter at the bottom of the booster. If the gauge goes over the booster at any point the booster has been altered. This is the most common alteration of the 600 carburetor and power gains of up to 10HP are common by
    tapering the booster below the .615 allowed. NOTE: The booster has a normal taper by design but should not be less than the gauge of .615. This is a very important area to check.

    78607 Booster Locating Tool - This tool is used to check and see if the booster has been relocated and raised in the main body. The gauge is designed to set on top of an HP main body side to side directly over the booster.
