Air fuel ratio tracking rich
I took my V-6 Tbird to a chassis dyno and on this one pull the a/f started to track rich with power decreasing at the higher rpm.Can you tell by the graph that I need to go into the emulsion and make change to the top hole.This is a 9380 850 with a blp metering block I’ve already changed a lot on this carburetor to get it to this point it was pig rich in the 11.4’ a/f with the stock meter blocks.Right now it has 84 pri 87 sec jetting with the stock high speed bleeds on both sides.

Your description isn't very clear... what changed between _3 and _4? Was there a carb switch? If so, what was the first carb? Thx
