Hello I just bought my first opitus 1550 and I have a question. Does the preheater tapered nozzle have two holes, one on flat service and one on tapered side, or does it have 3 holes. the third one in the middle of the nipple point like the Petromax? *Moderator edit: As seen in the illustration here Spoiler in the topic this post was split from.
If memory don't serve me wrong, I'm pretty sure that Optimus just have the two first holes you mention, and none at the very tip.
