MF these carbs can tolerate pretty much anything I have seen them half full of water because they have been left in the rain with no cap on the snorkel, strip the carb, give it a clean and they will work fine. Best carby by far I have ever seen. As for any mowers you have with the earlier alloy type carbs I would just run them, turn the fuel off and let them run out of fuel. That method has worked well with Victas for over 50 years
