RWA 1218 Carb restrictor kit is designed to use in the Holley 350/500 2bbl carburetors. These carburetors are designed for use on V8 engines and will run too rich on initial acceleration on a 4 cylinder engine. Our restrictor kit eliminates the bog by reducing the fuel flow through the metering block. The restrictors are installed under the power valve in the metering block.
The kit includes:
- 2 brass restrictors
- 1 drill bit
- Instruction sheet
