Just because the plugs are new, doesn't mean they're the right kind.  Make sure that they're NGK D8EA or DR8EIX.

Since you have an 82, your slow speed (idle) jets should be removeable (my early 81 has a pressed in slow speed jet).

Did you remove them to clean it?  It's down the tube that is plugged by the rubber plug.  You would need a small flat blade screwdriver to get it out.

Did you also remove all of your emulsion tubes to clean them as well?
