I had the car out for the first passes last night. The carb was too rich. The main jets are 143's and I will jet down to 136. The primary metering rods are marked 1940. Can someone tell me the numbers for some larger metering rods. I need to lean out the primaries as well. I like the A/F between 12.7 and 13. Last night it was
in the low 12's and high 11's. The last pass I made it was 11.1 and the car did not want to pull at 6600 rpms.
The temperatures in the 50's with a corrected DA of 1500 feet which is great for us in the desert since our track is at 1250 feet. Unfortunately the humidity started at 49% and by the end of the night it was at 72%. Those are really high percentages for us.

Any help will be appreciated.
