Look here's something simple to try.
Are you unhappy with your current torch?
Drill 2 more holes in it and try it
Keep enlarging said holes until you get the desired result.
To be honest you don't need to spend money on a regulator and a new torch unless it quit working.
Air to fuel ratio will help you more than spending $60 on a new torch.
Unles you have the first version unit the torch they are talking about isn't like the one you have.
I answered your question in the other thread,Home Depot only sells 2 manual torches that will work with your unit because the other ones are to long.
One torch is under $15 and the other over $20.
Amazon is not playing switcheroo on anyone,the torches are discontinued (look at the date)
