That seems to perhaps negate the comments by 'surlypud'(Chris?) in post #11 of the thread 'Propane and propane related accessories' (https://www.velocipedesalon.com/foru...ies-35064.html) mentioning how the combination of a Midget's smaller diameter mixer + oxygen concentrators' limited output pressure can cause a lack of O2 supply issue when a large flame is desired.
If you recall that meeting with 'surlypud', I'd appreciate YOUR clarification about what the problem was in his case.
