Yes, this valve is going into the KingCat I've been working on, it came with an older Jetronics valve ( no fail safe ) he bought the new valve because it has fail safe build in, we have used Tams fail safe valves before, many times, we both thought that the fail safe in the new valve was like Tam's.

Clearly an end user misunderstanding.

Now I know for sure that it is working right.

Thank you for the clarification Dave.
