When I removed the carb I also took out the reed block-its a boyesen block and the previous owner tried to modify another brand reed valves in there with some modification on the holding plate- the reed tips was also open- will replace them. What is the correct fuel? Should I rather use 93 unleaded?

No, stay with 95 unleaded and 50:1 but get a correct spark plug.
