stator /flywheel related question

[new2_2stroke]

put adj timing plate on and it states that you should adjust the space between the pulsar and the little things on the flywheel to no less than .020 does anyone have any recommendations for this?
I put a .022 between it and tightened down for now unless someone has a better recommendation. I did not have a .021 and it said to get as close as possible but no less than .020.

thanks for any help.
