Nikki Carb

[bob]

Cleaning carb on a Briggs and Stratton 21m114-1362-E1 which has a Nikki carb. Removing plastic part to look at bowl when I thought I heard something dropto floor. I could not find anything but I am wondering is anything like a spring on the float/needle. I can not find a good parts illustration to tell for sure. Float itself is not level so that is another reason I think there is. MY mistake and now I need help. Thanks

I dont think this one has a spring, look in the fuel transfer tube and see if the main jet is missing.

Edit: I did find an IPL that shows a spring that was used before code: 08050700. I'm sure one of the more proficient guys will be by later and can help more. Spring part number is 695422.

Probably the little brass MAIN jet from that single barrel Nikki.
It will need to be a snug fit or good or ring when going back. I seem to think some of them has to be installed and removed from the top of the emulsion tube on some Nikki"s.

Here is a link for working on several carbs.
Just choose Nikki and scroll until you see yours.

The float valve is a plastic spring loaded version so the float will droop when the carburetor is inverted.



As said it is likely the main jet that hit the floor. I have learned to be very carefully when disassembling any Nikki carburetor that has the plastic fuel transfer assembly. When I first started repairing these I too lost several onto my shop floor. I now disassemble in a pan with high sides just in case the jet falls out. Also be careful using pressurize air as I had a couple jets to find their way out in my yard. I decide trying to use a magnifier glass was going to help.

there are also some nikki carbs that have a spring that holds the nylon float assembly tight to the gasket so if the main jet is there, you may have lost your spring..
