I am not a chemist but I notice an ammonia smell in the charcoal gas when running and I think that has something to do with the butterflies seizing up where the shaft goes through the pot metal or whatever the carb body is made of. I spray a couple of squirts of liquid wrench at shutdown to lube it and work it back and forth to coat the shaft.
