I am halfway through rebuilding my stock nikki. When I removed the accelerator pump and diaphragm I noticed that there was no return spring.
Any ideas on where I can source a new one since it does not come in the GP Sorensen kit?
The car has been sitting for a couple of years but did run before then. will it be able to function without the spring since it did before?

 

the accelerator pump diaphragm will not work properly without that spring in it. no idea where to get one unless u can get one from someone here.

 

Thanks for the help rxtasy3.
I figured as much. But was hoping by some miracle that it was not necessary. I guess I'll just finish the rebuild today and wait till I can get the spring before I put it back on the car. I just wonder how there was no spring in there in the first place

Anyone have an extra laying around?

 

Now I feel dumb. The spring came out and has been sitting this whole time under the throttle body I guess I missed it.
Im putting everything together now. Hopefully I didn't mess anything up.
sorry for creating a useless thread

 

Hope you know where your check ***** and weights are... those are the worst items that go missing on carb rebuilds.

 

I made sure to keep everything very organized. The spring was the only questionable item and must have sprung down and out of view when I first opened it up.
I actually finished the rebuild about an hour ago. If it was still light out I would have reinstalled it too. I am going to do it on wednesday. Looking forward to it

 

in case anyone was interested. the car started up for the first time in about 7-8 years after a little coaxing.
There was a gigantic plume of smoke for the first couple of minutes. I heard a firetruck with its sirens soon after. It wasn't for the rx7 but I thought it was for a second.
I think its running a little rich right now. Im going to put some time in to get things right this week.
