About this document

LPG Carburetor Tuning Guide by Costas Georgatos is a document available to read on EtoBox.

The document provides guidelines for tuning a GRA Gold series carburetor in three stages: [1] Idle mixture and speed settings using the idle mixture screw and idle jets, [2] progression circuit settings using progression hose jets, and [3] main metering circuit settings using metering rods. It recommends starting idle mixture with a 2.2mm jet, using larger metering rods for leaner mixtures, and maintaining progressive enrichment from cruise to wide open throttle.
