I did lots of research and found it has a smaller jet in it than the SOL and SUMO. I ordered a new jet and installed it. It didn't work as planned and was not as efficient as with the standard jet. I put it back to stock and it works very well and is fuel efficient once again. Thank you JetBoil for engineering and producing a great product.
