Hello!
I have this service manual that is more confusing me than helping. At step by step instructions it says to advance the throttle until the throttle 2 dots pick up marks are aligned with the timing mark.( 2 dots on my flywheel are at 12° ATDC).
At the end of the manual at appendix it says to adjust to the first mark after the first dot which is at 2° ATDC.
If someone know the right setting please help.

Thank you for your answer but I'm looking for the idle adjustment point. I guess 24 is for the high..

Book calls for 2°ATDC but due to age and wear anything close to this will be fine. The motor will tell you what it likes/dislikes
