I'm not a fan of the mushroom burners. They can be very fussy. I like the Mamod TE wadding spirit burners more. Tony Green sold high quality versions of various sizes. Depending on the engine, I run 75% or 95% ABV.  The surface area of the burner makes a big difference in what ABV as well.

On one of my Märklin 402 engines had a leaky rusty (dangerous) tank, I converted it to a leak proof wadding burner.  Runs fantastic and much safer.
