This kit is about as close to a master kit as you will find. Lots of parts not usually found in today's kits. Mercarb marine carburetor rebuild kit.
UPDATE - The original float was a Nitrophyl, but we have discovered it does not hold up with today's fuel. We have found the current made Nitrophyl float does not hold up with today's fuel either and we recommend changing these out with a brass float.
When setting the float level, set it level to eye and check the float drop to be sure it isn't pulling the needle out too far.
Don't forget to change the float at rebuild time. These carburetors have nitrophyl floats and they absorb fuel over time. We now have brass floats available for these carburetors.
Your carburetor may only have part of the carburetor stamped on the carburetor. I.E. 1389-9563A1 may be indicated as 9563
Mercarb has 1 idle mixture screw.
