That is a sharp engine (looks unfired) I wonder if Wilesco got a bump in sales after Mamods demise ?
Currently unfired, didn’t know if it would come with Esbit or gel burner… ended up ordering gel burner from Forest Classics, but I wasn’t home and it’s now sitting at the post office. Hopefully firing it in the next week or so.
Just for general information, Sterno has always worked just fine for me in a standard Wilesco "tablet" burner. It does NOT leak out the holes when on fire, but rather turns sort of leathery and becomes a bit stiffer. The side holes actually help it burn better.
If concerned about the minor residue left behind, it does wash out with soap and water, or you can line the burner with foil first and then just dispose of it that way.
