for garunteed clean carbs, use the following...
1) strip the carb completely and throw everything in a clean tub with coca cola in in (diet or ordinary, doesnt seem to matter)
2) leave to soak for 2 to 3 hours
3) remove and wash very thoroughly in warm water with lots of fairy liquid
4) remove, leave to dry for 30 mins...
5) wash over with a new paint brush and some cellulose thinners (or equiv)
6) blast off with compressed air and re assemble as you go...
Have done my carbs countless times, plus the lawnmowers etc.... works a treat everytime
