not sure what u mean by spongy. just make sure there's as little slack as possible in the throttle cable. it's been a while since i dealt with the stock carb but r u sure those fuel lines aren't backwards?

 

if they were backwards it wouldn't run at all would it?

 

By spongy I mean it's really easy to press and not very responsive. Also I just realized that I can rev the engine by opening the secondaries. Shouldn't it bog down if open the secondaries at idle?

 

the return spring may just be weak. i too have been able to rev one with the secondaries. as far as i know it would still run if the lines were reversed.

 

The fuel lines aren't supposed to cross are they? I think they're supposed to run parallel to eachother I'll see if I can find some pics. On my other carb if I opened the secondaries at idle the car would stumble and die but that carb was pretty rough so idk.

 

the fuel lines crossing over each other makes no difference. like i said it's been a while. but i believe the larger of the two metal lines on the carb is the supply side.

 

Ok if the bigger one is supply then mines right... I believe... I'll check

 

ok so i twisted the return spring so that its tighter and it feels better now but it still feels like im lacking some power and throttle response. gonna fine tune it and try to figure out how tight the throttle cable needs to be tomorrow. any other suggestions on what to check/adjust?

 

Bigger line is supply - small one is return.

 

when's the last time u checked the timing?

 

yeah the timing probably does need checked

 

ok so the gaskets in the rebuild kit that go between the spacer and the carb and the spacer and the mani. am i not supposed to use those at all? i put them on but ive seen people comment that your not supposed to. could that be the problem?

 

from what i've read in the past the carb spacer has the gaskets made on them so no need to use another one.

 

In that case I'm gonna need to find a new spacer cuz the gaskets on mine are in rough shape.

 

The lines look okay. The larger line is the supply and smaller line is the return. Last carb rebuild I did I had to adjust the throttle cable with a few spacers due to slack.
Adjust the cable, fine tune the carby, adjust timing ( could be off) and de-grease the hell out of your engine bay!

 

just the sides not the rubber tip

 

i never burnished mine and had no problems the car ran great after i rebuilt it but just didnt have enough power so i got an aftermarket one...

 

ok so on friday i got the rebuilt 83 nikki put and it ran but felt like it just needed some adjustments. it was still running fine on sunday then on monday i went to start it and got nothin and im relly having trouble tuning the carb cuz im used to tuning and adjusting my 79 carb. so my question is can i swap my 79 carb base onto the 83 top and mid section?

 

well ive got the 79 bottom attached to the 83 mid and top of the carb so i guess when one of my parents gets home ill let you guys know if it works

 

Why not just tune the carb you just rebuilt instead of taking apart two carbs?


I dont think it should be a problem. Im not sure what the differences are between S1 -S2 carbs. Maybe the jetting might be different? Why not try to fine the carb you just rebuilt(83)? Its not hard especially if you have a wideband.

 

cuz im used to the a/f adjustments on the 79 carb and couldnt seem to get the 83 carb tuned and then it started flooding and wouldnt start

 

If I were you I'd try to tune that 83. Thats just me I guess. Turn those screws all the way down and start again!

 

well ive already got "frankincarb" assembled so im gonna give it a try but if it still doesnt work then im gonna take it back apart reclean it and fully assemble the 83 carb

 

Joe, you have been told to keep your related threads in one thread? you already asked this same question in your existing carburetor thread!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Also it would be appreciated if you would start thinking on your own and you now have the record for the amount of questions that you have asked on this site.

In the future if you cannot find a answer(most of your threads started could have been answered by searching for more than a couple of minutes) then find a related thread and bump it up so we don't have so many repeat threads on the subjects that you are asking about.

 

AMEN TO THAT BROTHER! lmfao! Not trying to be a dick but I noticed the amount of similar threads posted on the same topic. Lets send him to the Newbie section! j/k
