I am stripping my nikki carb down to the essencials, but the diagram i have of the parts that need to be removed is if you want to go with mechanical secondary, does anyoen know which parts i should not remove if i want to keep the secondary's as is?

 

Welcome to the forum, there are many threads on the Nikki. Most of them have been archived for reference.

You can find more of these related threads by searching with either the phrase(s)
nikki, or carburetor, or by just the phrase, "Intake" in the archive section.

 

Ok, go to this link https://www.rx7club.com/1st-gen-archive-71/intake-carb-rebuild-how-strip-nikki-down-648376/

and scroll to the third post ( i think its the third one) anyways it is on the main body diagram. and you will see the "sec mechandaries" in a { , just take a close look at the vaccum diaphram and the linkage and simply keep all those on and remove the rest of the stuff that is in red. also make sure you read rx7-carls post on it!!
I have never stripped a Nikki Down , so if Im wrong on this then I am sure that someone with more knowledge will correct me, or let you know.
