Hey guys I got some propane today and I've been trying to get it to work but I just can't get the mixture right. I have an 18" chamber (3" diameter) with a normal bbq sparker. I've tried putting a lot, and putting a tiny bit. Any tips?

Um....You need to make a propane meter. Look at the wiki and search around for advanced combustions. I really suggest you do that before you get hurt. On burntlatke.com there are fuel tools and ratio tools for you.

Make one? Gosh maybe I'll just stick with aqua net. Works well, everytime. We're trying the butane lighter method tonight. How could I hurt myself??

Propane can be pretty harmful if used incorretcly. Making one is simple, but like everything research is always helpful and quite neccessary.
