I've got a E4ME Qjet on a 305 in an El Camino. I have removed the choke plate and linkage, modified the secondary air valves to open completely, modified the secondary throttle plates to open completely, and removed the secondary choke pull-off linkage. It runs alot better thsan it used to, but as I am always looking for ways to get more power I am wondering if there is a way to gain power by changing the secondary metering rods. I am not opposed to any suggestions.
