Glad you got it running!Sounds like your original carb is the problem. Have you checked the idle tube to be sure it’s open? I use some carb cleaner, with the red extension tip, or if it’s bad, use a torch tip cleaner wire of the appropriate size to clean it out. A good way to clean a nasty carburetor is to spray it out with Mercury PowerTune. Let it soak for 20 mins. or so, then rinse with carb cleaner. Repeat as needed. The Power Tune spray will dissolve varnish almost instantly.
