I am experiencing a similar problem. It did not occur until I rotated the brass fitting for the fuel hose on the HSN assembly. Before I loosened and rotated this part the engine was perfect, and easy to tune. So I would carefully look at this area. In fact Ofna has an HSN assembly that uses a composite part that fits much better.
