What is engine? Have you ran a cylinder balance test? Loosen the spark plug wires, and with engine idling, remove one wire at a time. If engine dies when wire is removed, the opposite cylinder is not firing. If that is the case, Check it for spark. New engine may have one bad coil!

All that is fine. I noticed that the govoner is not regulating and now file is not being drawn to carb. Have to sufficate it to get enough compression to pull fuel

What engine? Pulse fuel pump? Suction to pump has to be vacuum tight or fuel pump will not work.
