The first carb I tried on the car was and EDL 1406. It had a huge bog transitioning into the secondaries. The EDL tech support suggested their AVS 650 cfm (EDL1806) carb would be a better choice due to its adjustable air valve on the secondaries. Here's the plot of the 1806 right out of the box. Note the huge oscillations in AF in 1st and 2nd gears. In third-fifth the AF calmed down. The car ran exactly as these plots indicate; run-miss-run-miss. IN THE NEXT FEW PHOTOS I WILL DEMONSTRATE HOW TO WASTE A LOT OF YOUR TIME TRYING TO TUNE THE EDL CARB. The problem stems from this car's light weight and high power that causes the engine to speed up very quickly in the lower gears. The carb's secondaries can't respond to the low vacuum signals and track the fuel mixture requirement fast enough.
