I never have had much luck with some type of snake oil freeing up valves that are stuck from setting long periods of time. Ones that are fuel gummed up yes, but not rust or carbon.
I would pull the head off and free them up. I have reused head gaskets on odd ball stuff before with good results. I usually clean the head and block up like you would for a new gasket. The spray both sides of the head gasket with Copper Coat spray. I hang the gasket up on a piece of wire. I put several coats on. Letting it get tacky between coats. Then install it when the last coat is dry to the touch.
I have done this on a lot of small engine gaskets. 90% of the time it works with zero problems.
You can also look at the valve seats. They may need resurfaced too. If they are rusty and pitted the motor will not run correctly until the valve and seats are at least lapped if not too bad. They will need ground if they are too bad.
