2 Circuit Gas billet metering block Assy Kit




Product Description

In the 1980's BLP Products was the first to introduce a fully machined billet metering block for performance Racing carburetors. Since that time BLP has expanded the billet metering block line to suite the amateur to professional carburetor builder. Black anodized Metering blocks have completely adjustable emulsion, idle feed and power valve restrictions for the most discerning carburetor builder.
