Yeah, soak the hell out of it. It's gummed up.. You don't want to break that jet off or you'll REALLY be up shit creek.. Dunk it completely submerged in a can full of alcohol or mineral spirits or something.. Shake it around every once in a while.. Then when ya DO go to take it out, loosen it like 1/8 of a turn, then tighten it back up 1/7 of a turn, loosen it 1/8 of a turn, tighten 1/7... and work it back and forth gently, until it spins easily.. :Those carbs are kinda hard to find now days.
