I've got 2 pairs of carbs here which need a good clean. I've had a search locally and cant find a lot apart from ebay which is telling me £50 for 2 carbs. Seems a lot to me when i could buy an ultrasonic cleaner for £40 and do it myself.

Does anyone have any advise? Am i looking at the wrong thing?

Educate me please.
