You want to know what the stock OEM jets are? Stock needles aren't adjustable. The fuel screw initial setting is usually 2.5 turns out from lightly seated. That will be fined tuned with a jet kit based on how it idles. If the needles are adjustable with an e-clip you can probably say there is a jet kit in it. Pretty sure the OEM sizes for Canada were 115 for all 4.
