You could try calling either Racing Beat or Mazdatrix.

GOOD LUCK!!!!

Ive been looking for the correct jet sizes for about a month. I have posts on just about every RX7 website. NO ONE KNOWS. I can get my car to idle and go through the whole rpm range without a problem but if I slam on the gas from idle the car just dies. What I know for sure is that size 90 pump nozzles are the correct ones. I have 240 main air jets / 190 main fuel / and 62.5 pilot (idle) jets if these are correct I dont know. I got those sizes off an online search and I cant find anyone to give a second opinion. If you find out please let me know

Those are the correct ones 240 main air/190 main fuel/62.5 pilot/90 pump nozzles. I got mine running perfect after hours of experimenting. The problem was the position of a cotter pin on the accelerator pump rod. The top hole is where it goes, also let it warm up before getting pissed off these carbs have to run for a few minutes before running right. LOTS OF POWER
