The carb is fully disassembled and when I had the main body inhand, a small metal ball fell out- where does it go?

 

in the little hole

 

which one?

 

There are two check ***** in the accellerator pump circuit. One in the fuel inlet and one under the discharge nozzle. There is also a weight that goes on top of the check ball for the nozzle. You may have lost all three.

 

There is a weight on both check *****, different diameter in size for each.

 

ok thanks

 

Hold up..!!!

I just cleaned up / rebuilt my nikki and I didn't see these check ***** or weights...? Although I did have the check ***** left over after it was all back together...

Do they just fall out or you have to remove / unscrew / turn upside down something before that happens..?

 

Until I have time to investigate this myself... back to the top you go.

 

Where the ap diaphragm is, at the top of the body is a brass plug, it is slotted for a common screwdriver. Under it is the skinny checkweight (Abbott) and under that is a checkball. In the center of the body (in the middle of the 4 barrels) is the AP pump squirter. It has a double slot for a common screwdriver. Under it is the short fat checkweight (Costello), under that is the other checkball.

 

Here is an exploded diagram of a nikki carb for you. If you want to download it to print, or save it to zoom in using imaging software, I saved it at a higher resolution at this link:

Hope this helps.

 

54 and 55 is Abbott

60 and 61 is Costello.

Thanks for the scan.

 

Thanks Carl for the advice. I didn't touch those... and that's why I had the new ones left over. Will that really make a difference..?

Thanks nos-595, a visual alwyas helps ALOT. Did that come with the rebuild kit..? Mine came with a overview of a 80 sumthin honda... ???? wtf

 

Came with an old rebuild kit from 10 years ago or more. I keep in around for reference just in case a long time passes between rebuilds. I did them every week at a shop I worked at years ago. Now I rarely do rebuilds so I find the sheet helpful. It is well used as seen from the grunge.

 

what do the 2 check ***** do(what would happen if you left them out in a rebuild)?

 

They stop fuel coming out of the accelerator pump nozzle when not in use as well as keeping the circuit primed. You need em.

 

think I could find a ball to replace them if I were to say...lose one?

 

Ball bearing maybe?
