If you pop float bowl off you will have two jets.
A slow running jet and a main jet.
Just unscrew and replace.
1st pic - mixture
2nd pic - bowl drains
3rd pic - fuel line I think. They have no vacumn take off on the carb. Most bikes take vacumn of one of the inlet manifolds
4th pic - Those pipes that run along the bottom of the carb hook up to the cooling system as Kawasaki had a few problems with carb icing so to combat that they ran warm coolant through them
I think you'll spend alot of time/effort/money getting that all running right tbh
What car is this going on? Are you sure it's worth the hassle?
