I'm converting my Spec RX-7 to ITA and have a few questions. The carb is currently a new stock rebuild, I plan to leave it that way for now with the exception of removing the emmissions stuff.

Questions:
1. Are you leaving any of the advance mechanisms in the dist? Or removing them all?

2. Is there any need to retain any of the rats nest/solenoids? I *think* it can all be removed legally and should only make a rough idle - but not 100% sure. Is the shutter valve in the intake manifold considered part of the emmissions system? Once the emmissions are removed, does the ECU (is that what they call it) do anything?

3. On my '82, there is a vent from the oil fill tube that runs into the side of the carb - is this just a crankcase vent? And if so, should I remove it and plug the hole in the carb (with epoxy, or ??)?

4. Can the hot-start assist be removed? And if so, is there any reason to do so (other than uncluttering the engine bay)?

Thanks.
