Well, replaced the carb with a supposedly rebuilt unit: never thought (I know, rookie!) to check if the gav would turn prior to installation - and now discovered it won't turn either direction. Gav on the old carburator turned perfectly, so the bind must be in the new one. Any suggestions for me? I am hesitant to force it to turn.
Also, any recommendations to whom I should send the old one for a quality rebuild?
