Nikki Carburetor for Hustler Super Z Flooding

[bmyownboss2005]

Where can I find a rebuild kit for a Nikki Carburetor? It fits my Super Z
FH721V model number 926378. On the carb its stamped
Nikki 7809
150 03 7117
266-642
I am having a problem with it flooding and gas filling the intake.I had this problem about two months ago and I just replaced an o-ring at the main valve seat. Why is this problem still bugging me? Can anyone help?
Thanks

A Kawasaki dealer would be your source for any of those carb parts.
It likely needs the o-ring again, the fuel today causes them to swell at times.
