Alrght guys, Im on my 5th Nikki Rebuild and Im loving it. I have followed all of my instructions as per Sterling's website and Glazedhams instructions in the archives. My question is besides dipping the carb in carb cleaner, what other methods do you guys use to clean them up? Also, I would like to see pics on how you set up your mechanical secondaries and emmisions block-off's. Or any tricks that you guys use. Pics would be nice. Thanks

i'm sorry i have no answer for you, but i would like to know if you have the links to the instructions?, i've been looking for something similar and couldn't find anything, i rebuild my carb with my uncle's help but it's been a good 4 years since that happened and i can't remember exactly how we did it.

Mine worked better before she was stripped, so I dressed her back up.

sterlingmetalworks.com this site is freaking amazing. Read it from beggining to end he provides alot of info. Also if you go to page 3 in the archives Glazedham42 has a great write up on rebuilding the carb without all of the emmisions junk.

ray green awesome work! How do you go about getting it so clean? I also have a concern. I was cleaning a carb last night with a Q-tip, in 2 of the orifices i stuck the Q-tip I heard a pop and when I tried to extract the Q-tip there was a bit of resistance. Im at work so I dont have any pics but Im hoping I didnt ruin this bad boy. Could anyone think of what I might have done improperly? Once I get home I will identify the orifices and list them. Thanks Again.

First, I gotta say thanks again to Vipernicus42 for taking the time to actually do this in thwe first place. It has been invaluable to me! Here is a link to a tutoeial he wrote some time ago. It is easy to follow, has pics of every step, and is so easy a caveman could do it! Anyone stripping a Nikki should have this.

Hope this helps, and hope someone pins this link to the archives! So everyone can use it.

I should have been more clear, that's Diving Driver's carb, not mine!

It's the best looking rebuild I know off.

Training the preying mantis to eat carb dirt was the hard part.

Question for the class: can anyone point out the "assembly error" in the 2nd pic? Something's not where it should be!

^yeah it has an arrow pointing to it.

Just remember that there is still a huge difference between a stripped Nikki, and a Sterling Nikki.

clubber

I wouldn't know. 5 months and still waiting for my sterling. I wish He'd get back to his carb business.

BZZZZT!

Nope, that part is right where it belongs. That second solenoid on the right side of the carb indicates that it has vacuum power valves, which were used only on a few variations of the Nikki. Other versions just have a flat land there with no hole in it.

Anyone else want to play?

rxtasy3

iTrader: (2)

aahhhhh. all the nikkis i've delt with didn't have that solenoid on them.

Only shows up on the 1980's, and on the 79's except for the non-California Manual Trans versions. Goes along with several other internal parts differences.

I've got 2 Nikki's torn down right now, about to build one.
I was wondering about the emergency return spring. In a thread in the archives by Jeff20b, he has removed it, IIRC, Sterling retains it on his builds. Anyone experience problems running without it?
Here is the thread, https://www.rx7club.com/1st-gen-archive-71/intake-nikki-mani-670456/
In the pic, the red arrow points to where it would be, the blue one points to a good view of his AP lever mod.

Sterling figured out a neat trick where he drills a hole in the upper hardware near the choke connector and routes the emergency return spring rod through it to act as a throttle return spring. This eliminated the entire bracket and stock throttle return spring from the area of the carb indicated by your red arrow. The short story here is that it allows you to take off the carb top with nothing more than a screw driver and a 14mm wrench. It eliminates the need for a needle nose plier to take the stock throttle return spring off. Plus it further simplifies the carb for your convenience.

I attempted this mod once but had to move on so I never figured out what all is needed to employ an emergency return spring as a throttle return spring and make it work. When I asked Sterling if he'd be willing to give me some pointers, he flatly refused. I guess there are some secrets the master needs to keep?

Very interesting, heading to garage now.

I found some pictures on my hd that sort of show the return spring mod.

Jeff20B

And here is a very clear picture of the mod. Sterling indicated it is an early carb.

Stevan

Thanks Jeff, after tearing parts off a 3rd carb, I figured something like that. The last pic you posted looks like there's a custom connection on the shaft to enable the spring to be closer to vertical, and eliminate an extension of the throttle bracket, or use of a modified main spring bracket. Here is a photo of the bracket removed, and the spring/connection reversed so it's closer to the carb body.

Stevan

Pretty simple, yet ingenious.<Had trouble spelling that.
I was thinking of modifying the brackets, but fabbing a new linkage on the shaft is cleaner.

I've been pretty ruthless with mine, removing as much as possible, still got a few more things to do to clean it up as well.. Included a close up of the mech secondaries mod, the linkage arm I used is from the diaphragm box -> secondary tab. It gets them open at around 1/4 throttle and goes hard.

Thanks for the pics guys! I will be posting up pics of mine this upcoming week, once I get my hands back on my digi.
