The most important part of cleaning a carb, is making sure there are no blocked passages or jets. The most common cause of poor running is either a poor state of tune, or a blocked passage or jet. Debris from the fuel tank (such as rust), dry rotted rubber from a fuel line, or varnish from old dried up fuel are all common causes of blockages.
