Comet Timing Gears

I have recently changed the alloy idler gears on my comet for steel ones. All the timing marks lined up on removal and on fitting the new gears. The only problem I can see is with the breather cog as when the "B" mark is just leaving the "B" mark on the large idler, the slot in the breather is at 2 o'clock and not pointing straight down as per diagram. Should I set it to the "B" mark or with the slot pointing down.
