Gap it to 25!
But before you do that adjust your valves to .004 intake and .005 exhaust.

Have you tried a larger pilot jet?

Sorry missed the 2t part. Still gap your plug to25.
Have you cleaned the carb? 2ts are especially sensitive to dirty jets as they have smaller pilots (idle) jets. And new does not mean you don't have to clean the carb. My Roman 150 came with a clogged up idle jet straight from the factory.
