From the looks of those hoses on the vents.....somebody has been fooling around with that carb before you got to it.

Here are stock carb specs:

You most likely don't need a rebuild kit - just a good cleaning to get the crud out.  Most rebuild kits don't likely have the proper jets anyhow.

I would suggest starting with a #150 main, and a #52.5 pilot jet if you are near sea level....over 2,000 feet a #50 pilot.  Then replace the white spacer on the needle with 3 washers (size #3 machine screw - get steel as brass often has too big of an outside diameter).  If you end up having a slight lean surge at very low throttle settings - remove 1 steel washer and try running just 2 washers.

Can you show me a photo of the other side of the carb?  I want to see if somebody took out the brass plug over the mixture screw......and see if there is a port for the charcoal canister on the California model carb.
