Re: O-Ring replacement for the needle packing washers?

quote FrankR:

I may be wrong, but I don’t remember a TN as having any packing on the high speed needle. Probably has something on the slow speed needle though. But I admitted I may be wrong.

That’s right. There is no packing on the high speed needle assembly for the HD, TD, and TN models. The low speed needle, however, calls for two packing washers. They are of a smaller size than the ones used later in non-rotary valve motors.
