041 Jet Install

[PT81man]

OK, so I took the carb apart, cleaned, and re-assembled but did a novice thing and did not note which jet went to which position. Is the jet with the step in it the High speed or Low speed? I understand the High speed is the one on top and should be 3/4-1 turn out while the Low speed is on the bottom with 1-1 1/4 turn out.
This is the last of the rework on this saw. I am just waiting for the correct air filter.

Well, I figured out which needle goes where and got it running fine. I am waiting for the correct air filter to arrive on Tuesday. Next question, the serial number is 113368681 which translates to an MS 270 or MS 180 built in 1983. All parts listed for 041 FB start out at 1110. What is correct?
