i adjusted the carb adjustment but it still surges a bit. is there something on the governor that i can adjust?

I will offer the simple fix.... clean the jet with a piece of phone wire.
If it seems to be OK at an idle or with 1/2 choke, it is pretty often a chunk of something is restricting the fuel flow.
After that there is an adjustment on the governor. I am not too wise about it, but it's in the service manual.

Is it surging at all throttle settings, or just at idle?
The bumper spring on the governor can be turned in, but if you turn it in too far, it will affect low idle RPM's.

Rob, is this a new problem? If its old, it could be mismatched parts in the carb.. Ed

Long time problem? Could be fuel flow, low fuel level in carburetor bowl, or partially plugged main jet. New problem, partially plugged main jet.

i don't believe its mismatched because it ran well before

I vote for the main jet..... Can't hurt to clean the strainer, fuel bowl too.
Shut the fuel off, 3/8" wrench, let it drain as you pull the jet out (brass/bronze 'nut' on the side of the carb).
You can just blow it out too.... but a thin piece of soft wire works well.
