Trigger pre-travel has been successfully reduced by adding a set screw in the top of the trigger where it makes contact with the disconnector. This also makes it adjustable. Trigger pull weight can be reduced by cutting a new angle on the sear, I've done several and prefer this method. Some have been successful tuning the pull by bending the springs and/or clipping the hammer spring a little. My 60 became unreliable with tweaked springs which is what lead me to working the sear.
If you need accurate rimfire information the best forum is Rimfire Central, the link below is for the Marlin semi-auto rifles (like the 60, 795 & other variants), but they cover nearly everything else rimfire too.

Article tells how to drill thru side of unit to get to points needing work.
No drilling or special jig required to work on a Marlin semi-auto action assembly (60, 795, 99M1 etc.). All you need is the proper procedure and it comes apart without any surprises.
I did find this article. "Working Marlin’s Model 60 Successfully By Frank Fry
" I don't think it's the one you're referring to because it's well over a year old and doesn't mention any modifications. A link to American Gunsmith and/or to the article would be nice if you have one or both. I'm curious as to what and why they're drilling.
