Float bowl question
We have our carburetor apart. I see the float rods that the floats slide up and down on, have a little cap on top. Never seen this before, in my limited experience. What are they for?
We have the carb apart because it is spewing fuel out the overflow. Suspect the float valve. Does anyone know the measurement to set the float height. We have it at 23 mm now.
It is a 1994 400 L 2 stroke

Caps were to keep the floats from sliding off when you removed the bowl but not needed for the carb to work right once the carb is back together. I've found plenty of these caps missing or eaten up by gas over the years.

Here's a pic of a similar Mikuni carb with the float arm correct. Bend the small tab if needed for adjustment.

Thanks.
The little end caps have been removed and will stay off. I like to shake the floats a little to be sure there is no liquid inside, whenever i have them off.
Rebuild kit has been ordered.
Our float needle valve had quite a grove in it , which is likely the source of our leaking problem. For fun we put the needle in a electric drill and using 1200 sand paper took the groove out. Then used polishing compound to bring the tip back to mirror finish. Also put polish compound on a Q tip and cleaned up the the brass housing the needle goes into. We will see if it works, for the 2 weeks when the new bits arrive.
