Jetting Question 1985 250r ATC

[MN250R]

Hello,
Just wondering if anyone knows what the jetting was stock on a 1985 ATC 250r. i know i have to do some plug chops, but was wondering if this setting is close or kinda rich on the pilot jet size? seems to smoke a little at take off, im running 40.1 amsoil series 2000.

I looked in the carb , and have a pilot 52, 142 main jet, neddle clip in the middle position. Air screw is out 1 1/4 turn.

Thanks! :)
