Zargon,Why not try the second,and then third dent,out.This should be for 1.5 and 2.0 gms.I believe the little weight has a set screw that may be able to lock to an intermediate position(more approximating the 1.8 gms).I hope this can work out for you,as I,myself track at 1.85 I have sometimes wondered if I should do the same.I'm too lazy I guess.Also,as the record is being tracked,look at the cantilever,from straight on(front of arm).If antiskate is correct,there should be no leaning(drag)of the cantilever in any direction,to a significant degree.Sort of like,if you considered the cantilever and it's reflection,in the lp to be ONE continuous line.Viewed from straight on.Hope this helps.
Best!
