    I was pre-heating my 8r using the regulator to hold the heat shield up so the tank would warm more quickly. I couldn’t recall hearing or reading about anyone else doing that

    I can’t be the only one…

    @E.B. Do you find that it makes any real difference to the start up time? Mine has the later key type control (similar to a 123R) so it would probably get too hot to touch if I left it there for too long.
    Regards

    I allways remove the heat shield before priming. Put it back when the burner is hot.
    My oldest 8 has a flatter tank lid, so the heat shield can swing over to the front of the tank.

    John, It definitely improves the start up time.

    Quite honestly, I can’t imagine trying it with a regulator key, even if it is possible. I have cooked my pinkies enough times in the past with my 71s and 123s.

    I try to roll the shield up some if it will stay. On my 8’s I use a Tilley torch placed by the burner and pipe from the tank. Did that this morning on a nickel 8 while backpacking.

    Never thought of that, but what a great idea!

    Actually, half of a torch, sorry. I've done this on my 8's. The pedestal ones I fill the preheat cup too, that seems to heat the burner better.

    In colder conditions, this method is recommended.
    ...In fact, the PT 1 (8R clone) user manual states: "raise the screen (heat shield) during warm-up"

    Yes. Maybe even required.

    But, my experience is that a small flame after pre-heat continues to heat the stove. I enjoy watching the progress of the flame.
    Why hurry? [If not in the colder conditions? ]

    Very good point. The truth be known, I am seldom or ever in a hurry. Like yourself, I enjoy the process but I also like to experiment and see what happens.

    Well said. Efficiency is not necessarily a rush.

    I pop a small length of fibreglass rope in the spirit cup, it prolongs the prime/helps limit it boiling-off :D
