new to rotary, 84 rx7 11a

I would get a used nikki to scavenge replacement parts. Try to get the same year or at least 84/85. The nikki is the best carb for the rotary but you can also get a nice Weber IDA setup from RacingBeat.com that can work with a stock 12A with some tuning.

Word of caution, do not use the new needles or seats in the rebuild kits. They are not made to very good tolerances and can cause flooding and stuck needles. Reuse the old ones as long as they look ok and seal up on the old seats. Also do not mess with the floats unless the gas doesn't come to the right level in the bowls. Another gotcha, if not using the stock fuel pump, the nikki really doesn't like more than about 2.5 psi.
