Have been researching what's need to replace a CIS on an 81 SC engine with carbs... and have also been asking the question of Zenith vs. Webers - but also what is the full package required to do the conversion. So far after reading the different posts here I'm finding:

- Carbs (whether Zeniths of Webers or PMOs)
- Rebuild kits (to start afresh) with appropriate needles, jets, etc for the engine
- (re)Sized venturis to match
- appropriate height stacks?
- insulators?
- Filters everywhere (as per Anderson recommendation)
- Fuel supply pressure reduction (whether via restrictors or lower pressure pumps etc... ideally with pressure guage)
- Recurve dizzy or vacuum delete backdate dizzy ?

Then nice optional additions:
- Backdate heat exchangers and banana

After that, I'm not looking to open the engine and look at high comp pistons and cams etc.
Am I on the right track? have I missed something?
Over here in France, I'm finding Zeniths easier to come by than Webers and with kits available online, it seems a reasonable option. From reading the different bibles and comments, I'll probably try to source Webers first as they appear to be the defacto standard for tuners, with Zeniths then being a viable option rather than first choice.

Thanks in advance for feedback, comments, etc.
