i got a can of aerosol carb cleaner from halfords, cant remember whats in it i think it was a mixture of very high grade petrol and liquid propane(propellant). i pointed the nozzle up the floatbowl drain tube and undid the tiny drain screw a couple of turns and squirted.
i then got the drain screw in my eye and a face full of carb cleaner, of course id undone the drain screw too much! it then took me and my wife four hours to find the screw somewhere on the garage floor, honestly, it was like something out of a carry on film!! i can laugh now, but that stuff bloody hurt like hell!
i know the carbs are a pain to take out but it is much easier to clean them on a workbench and you do a much better job, i used the lovely carb cleaner and a 1/2" paintbrush (learn again from my experience, buy a good quality brush that does'nt lose hairs everywhere).
i was surprised how "gummy" my carbs were for quite a young bike. also, that carb cleaner was expensive so if klaus says use ordinary fuel, go for it!
PS as klaus said its a very simple carb, dont worry about taking it to bits to clean out the jets and filters etc but make sure each bit is spotless when it goes back in!
