To replicate my J10 behaviour all I need to do is:

1. Start Engine
2. Slightly or Moderately apply pressure to the gas paddle.

The engine hesitates and sputters and some times turns off. RPM drops and is very unstable.

3. If the gas paddle is fully press RPM counter increase normally and gradually.

4. If Choke is turned on behaviour doesn't change

5. I had similar episodes and the day after everything worked normally however this time the behaviour is persisting
