Double Oil ? Is this 100:1 ? I ran 40:1 for about an hour now the engine at times will not turn with the starter seems tight ? I can however turn it with my hands and she fired right up. I am afraid the motor is locking up on me so should I increase it to 100:1 the rebuild company told me to use 50:1 , I decided to play it safe and run 40:1. Your thoughts ?
