i hope this isn't too far off topic, but i just took apart and cleaned the carburetor on my outboard engine, and I'm not sure if I lost a part or spring from my choke assembly? there's a short vertical spring that doesn't seem to pull the choke back into it's un-choked position completely. couldn't find any similar photos online. any help is appreciated.

What make hp and age I have old Evinrude repair file somewhere
 
They usually have a spring on the choke shaft and the one in the picture is possibly a detent spring , is there a notch in the lever that the spring could fit into ?

You can see the spring on the lower right where the choke shaft goes into the carby .

I found this schematic, but it doesn't show any spring in that location (blue arrow)

another question: this shows three gaskets 22, 23 ,22 together. (green arrow)

I put 23 on the other side. if wrong, there isn't a gasket at the other side? (red arrow)

thanks!

I can't really see. is the spring around the shaft?
 
The three gaskets = 2 gaskets and an insulator plate to stop heat transfer from the motor to the carby . Th red arrow is where the choke butterfly is located and the throttle butterfly is just below numbers 2&3 which are your idle speed screw and tension spring .
Can you post a few photos of the carby ? It is a cable operated choke so have you tried adjusting the cable so when the choke lever is fully in the choke is fully open ?

if in doubt buy a British seagull ;)
on a serious note, if you have lost the spring just use a rubber band as a 'return' for the choke.

I'm interpreting your diagram that the remote choke lever pushes and pulls on the cable, and provides the holding force for open and close of the choke butterfly valve. Does the parts list have anything noted about the choke parts. The diagram shows the cable clamps at each end, a spring would probably open the valve against the lever setting, which is controlled by the operator during start.
 
The reason you can’t see the spring is because the carby body along with the choke and throttle butterflies is one assembly (-1 ) so if you had to replace the carby body it would come with the choke and throttle already fitted but not the idle screw or air mixture screw as they are listed separately . The choke may or may not be fitted with a return spring but the throttle will always be , if you look at the choke.butterfly shaft in between the activating l horn ( the lever the cable hooks up to ) and the carby body it may have a spring wound around the butterfly shaft that hooks up to the activating horn and the carby body .

thanks I'll check that.
 
I'm going to try to add a small spring whether there was one there or not. then i'll try to start it when the weather warms up a bit.
thanks for all your help!

you don't have to change anything. That spring simply stop the shaft from rotating all buy itself.look at the picture
