Carb rebuild on 2000 model C90TLRY 2 stroke

[MAC ATTACK]

I recently purchased a new to me boat and had trouble on the water with low end missing, running rich etc. I decided to go ahead and rebuild carbs and put new plugs in while I am also attending to other maintenance items.

When reading the service manual and disassembling the carbs I got to the section of checking the "starter assy" (that's what the part is called when ordering).

I think mine is bad without even testing. Here is a pic of it, and it does not look like the diagram in the book.

If anyone has experience with these, am I in fact missing something on this? I already ordered one (ouch $$) but am really wondering if this could have been my problem to start with. What would a bad part cause the motor to do?

I am not new to boats/motors but am new to Yamaha and this set up.

Any help will be greatly appreciated

looks like it is missing the needle that fits into the seat if it is anything like the one on my C40.

It would not shut off the enriching fuel to motor after it warmed up and cause a over rich problem

Thanks. It was not in the carb either. I turned the key on and nothing on it moved after 3 minutes. Someone must have modified it or broke it and left it like that. I have ordered another anyway, and the carbs are soaking as I am typing. Hopefully it will run as good below 2500 rpms as it did above.

Thanks for the explanation!
