Aye, sounds like you are pushing fuel and oxygen out of your torch so fast it doesn't have time to mix.

Start with fuel only and get a small 5 inch long yellow flame.

Then add oxygen until the flame turns blue.

That should leave you with a monster flame probably pushing the burning flame off the face of the torch by a quarter inch.

Back everything down until you get some small blue cones at the base of the flame and then back it down some more to get the base of those to within a 16th to an 8th of an inch from you torch face.

That should leave you with a flame some 6 to 10 inches long.

You want to work in the last three inches of that flame.

You can turn it all down to a smaller flame for small work but you want to make sure to keep the base of the flame from touching the torch itself.
That can heat the metal up enough to bake the valves and even the hose connections which will damage the torch.

Stay safe.
Start slowly and just let your body get used to being in that position while you learn what the glass does.

33 is some seriously hard stuff and requires a heck of a lot of heat and also shade 5 glasses because it glows so much it can give your hands and face a sun burn not to mention what it will do to your eyes without proper protection.
