Installation Instructions for 34-105 Billet Metering Block

Thank you for purchasing our Billet Two Circuit Gasoline Metering Block Conversion Kit.

Installation is essentially the same procedure as replacing a conventional metering block. There are a couple

of features and tuning aspects of this metering block you should become familiar with. At the top of the

straight “V” is the idle feed restriction (see illustration below). This screw-in restriction controls the fuel side

of the idle and off-idle air/fuel mixture. Your primary metering block comes with .033” idle feed restrictions. The number

“33” will be stamped on the head of these restrictions.

The emulsion holes, the three emulsion bleeds in the serpentine slot are pre-calibrated and intentionally do not

have any bleeds installed. These pre-calibrated emulsion holes offer improved performance over your original

metering block and are adequate for the majority of most applications.

An additional feature of the metering block is an adjustable power valve channel restriction. These are

the holes immediately behind the power valve 1” hex head. The purpose of these restrictions is to add

supplemental fuel to the main well during wide open throttle operation or when the engine load drops the

manifold vacuum below the calibrated value of the power valve. In this metering block the power valve channel

restrictions are .059” and should have the number “59” stamped on the head.

CAUTION: Do not make drastic emulsion or power valve channel size changes as you can significatly alter the

air/fuel mixture ratio and could cause damage to the engine. It is highly recommended that when experimenting

with emulsion calibration you consult one of the many books available on carburetor modification and use one

or more devices that montors air/fuel ratio throughout the operating RPM range.
