I finally got around to getting my venerable Optimus 111B Hiker reworked by A&H- just got it back yesterday. Somehow over the years, I ended up with two different types of restrictor sleeves: #1 is the regular alcohol sleeve (I think!)- it has a lip (or flange) at one end and a pair of holes at the other. #2 has no lip at all, and has a pair of holes at EACH end............. My Fossil memory can't remember what they're 'sposed to be anymore! Can anybody help? Thanks!
I got one stove that had 2 restrictor like yours just try them both use the best one that works on alcohol
Welcome to CCS. The 111B shouldn't have any restrictor as far as I'm aware. Straight roarer burner - single fuel ie gasoline. On the later silent burner 111T one was for alcohol & the other, I think, was for certain grades of gasoline. I don't have my paperwork to hand but I'm sure someone will confirm before I do.
I've heard of one of the 111T restrictors being for gasoline. This is apparently supported to some degree by the fact that [air-] restriction may be reqd. when burning certain mixtures in the Pri 71. Some models had a restriction adj. on the bnr. bell; see here. A quick Google suggests that Benzole mixture is gasoline/benzene and Discol is gasoline/alcohol. Such mixtures might well require some form of restriction in other bnrs.
