Robin revs up and down? Please help!

At rest the govenor should allow the throttle to be fully open.
So you set it by holding the throttle full open and turning the govenor shaft backwards so as soon as it starts moving it closes doown the throttle from the fully open position.

Finally back at it again. Adjusted the governor per manual i turned as far as i could while holding the throttle open and it runs a little better but i noticed it wont close the throttle completely it only close to like half way.

Surging on a governed engine is nearly always lean fuel .
So the next trick is to heavily spray around the inlet with some WD 40 or sililar from A TRIGGER PACK.
You are looking for an air leak which will suck in the WD 40 and cause white smoke & the engine to change speed.
Second trick is to check the fuel supply is aequate.
If the engine starts uo OK and runs a minute or so then starts to hunt that generally shows the fuel line is blocked .
And don't forget the filter inside the tank.

need to clean the carb take it off and soak it in carb cleaner paint bucket with basket problem solved + empty fuel at end of season add stabilizer

just what u want to do make a sick motor puff white smoke get a rebuild kit use all of the parts!

Try holding the throttle in one position and prevent the surging and see how it runs. If it sputters or tries to die then you have a fuel problem. If it runs steady without sputtering and rough running then the problem would be in the governor.

9 out of ten problems are with the fuel you most likely have a problem with the carb

Thanks but i have tried all those things. I am give in. Sorry but both my experiences with robin engines have been bad. They may be good on other equipment but generators are not it. I had a generator that surged from the store. Ill likely replace the engine with a horizontal briggs or a Predator. I really appreciate all the help guys and gals super thanks.
