I would go back to the original carb, the new one is probably offshore junk. When you remove the bowl you will see a 'bump' on the center post, it houses the idle passage which tends to plug up. Remove the idle mixture screw then run a tag wire up the passage, the opening is in the threads so will take a little fishing to find. I use a welding tip cleaner.
I know your unit probably doesn't idle down but runs on the idle circuit until a load is applied and the throttle opens up.
