slow speed needle valve

[ron1960]

I have a 1972 evinrude model 40253E does anyone know if there is a replaceable slow speed needle valve seat for this carb. The schematic shows the needle valve but not the seat for the needle valve

There is not a replacable needle valve seat for your engine, the seat in the carb is harder than the needle valve.

Is there an easy way to examine the seat for damage if you do not have a bore scope and can this seat be repaired if it is damaged. The engine was worked on by people that did not no what they were doing, and I am afraid they way have damaged the neddle valve seat.

The idle fuel/air needle does not have a seat that can be repaired or inspected. If you are talking about the float needle seat then yes you can purchase the float valve and seat.
