Thunder Series Avs Carb Tune 6547 Rod
|
To fatten up the cruise mixture, while keeping the WOT setting unchanged, we needed a metering rod with the same power step diameter at the tip, while having a thinner part-throttle step higher up the rod. We settled on a 6547 rod, which measures .065 inch on the cruise step and .047 inch on the power step. The stock rods were 6847s, which measure .068 and .047 inch on the cruise and power steps, respectively. View Related Article
