I hadn't thought of using one of those trigger, I'll look out for an old one. My mates mum used to make grey vegetables in one when we were kids I had to clean some su carbs from a rover 2000, last weekend which had the float chambers half full of petrol tar as they'd sat for 15yrs, boiled the parts in plain water in an old saucepan. It all swelled and came off in about 10 minutes.Proprietary carb cleaner uses acetone as far as I know, used to be supplied as nail varnish remover amongst other things but used in fibre glass work etc.
