I just got an RX7 today,( I know, I'm excited too!) and it wouldn't run. It would start if you put gas directly into the carb. Checked incoming gas...good, one bowl full, one empty. I'm thinking a good cleaning will help, so.....I pretty much have everything aprt, and getting ready to reassemble when a tiny ball bearing falls out. CRAP!

Where does it go, and how many should be in the carb? I searched for nikki+carb, but got no good answers.

 

Ok I found some info and think I'm getting there. One thing though, the tutorial I read mentions :

"There are two check *****, and three weights in the carburetor. The two smaller weights and the check ***** are for the accelerator pump circuit.

The largest weight is for under the brass screw that is part of the richer coasting/decelleration circuit, and there is no check ball under it. (This confuses people, and they fear they've lost a check ball!)
Some carburetors do not have this weight and associated jets.

The fatter of the two smaller brass weights goes over top of the check ball located under the accelerator pump nozzle. The skinniest weight goes over the check ball located under the fat brass plug over the the accelerator pump housing."


I got the largest weight it mentions correct, and I think I have the one of the smallers right. What's getting me is...what/where is the nozzle??

 

Ok, heres a pic with the skinny weight and ball.

The other ball and fat short weight are here. In this pic, near the center of the carb where the stud goes you can see a brass bolt that has a cross on the top of it. Thats the nozzle. teh ball goes in the hole first, then the weight. HTH
