I also had to add weight to get my 2 burner Eno to sit level. Its no big deal, and actually makes the unit more stable. I used a lead weight I made from melted auto tire balancing weights. You can get them free from your friendly tire company. I poured something like 1.5kg liquid lead into a routed out cavity in a piece of
wood. Melt the lead outside in an old sauce pan with a
propane torch. I like the ENO, well made, easy to use, and keep clean.
