Thanks for the advice regarding the blast hole size. I'm in London at present
but will try opening it out next week (and fit a spark arrester) in time for
the BHR steam Gala on 2nd July.
Cheers
Ken

Hi Ken,
I have had this problem and solved it by increasing the diameter of the
blast pipe. I did it in increments of 0.5mm until I had the desired amount
of draw on the fire.
Cheers,
