Riding with the seafoam in it may do the trick. As for the airleak you can get some thing like wd40 and spray it around the rubber carb inlet while the engine is running. If the idle picks up you have found it. That doesn't always work, but it is fast. Rigging a spark plug up with a Schrader valve and connecting it to an air source, tdc of the compression stroke, and spray soapy water around the same area always works for me. If you try that with a two stroke, limit the air pressure to under 10 lbs.I use avgas to store and clean. It doesn't gum and as my son is fond of saying 'takes white off of rice'.
