i bought a vevor one ages ago forget the litres size but itll hold a four barrel rochester,wasnt expensive and i only used it again last weekend on a mates clogged up quad bike piece of #$%*,works wonders,ive cleaned a few carbs that were throw away clogged with tar like #$%* that wont budge with carbs or throttle body cleaner,i use a truck wash product here called chemtech ct18 and hot water,gets its all out man!!heres three photos of a maddass carb not run ten years,then after 30 mins by hand with carb cleaner and elbow grease etc,then after that 30 mins in the hot truck wash and vevor ultra sonic,dont go small get the biggest tank you can afford,i still think it helps to get the most crud off by hand first if you can.
