Ken,

There is a formula for working out the exact size of the blast pipe, I can't 
remember it off the top of my head but do know where to find it..  If you're 
still having problems let me know an I'll sort it for you.

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,
