Thanks for the input! The satio has had about 3/4 of a gallon through it, the last 1/4 of the gallon might be bad but it is in a sealed jug. prophangar1 what glow plug would you use for this application? I am using a OS #8! Chaser the motor will shut off at any throttle setting. It seems like the grimmlins are just flipping the switch and the motor dies. Michael the valve adjustment is true and correct that was one of the first things we tried right after the motor monster got into my satio. exeter_acers I did not change the fuel lines. It is less than 6 months old and I'm thinking about sending it in to be inspected what would ya'll do?
