just me I would take it apart & soak it in the soup (modern stuff ain't as wicked as the old formulas were) then rinse/clean it with solvent then clean with shop air then blast all passages with brake kleen the air blast again. & a good filter ahead of it. if you have to run E10 & you get another kit for it you might see if there are alcohol resistant seals/gaskets available. "the carb shop" in Eldon Missouri (google it) might have info as he is a top notch carb man (very expensive tho).
