Good to hear everything turned out OK. The adjustment is made at operating temp, idling, preferably in park...no nervous wives that way!

Chris Bell, the lock nut has a dished area on one side, fit the O ring there. In reality, it is not round, but a flat ring with a high ridge in the middle so you can peel it over the threads, and either side will make the seal. I had to pull it out again the next day, and reset it, smooth idle.
