Per Timney, lighter fluid is great for cleaning trigger mechanisms. The light residue left by the lighter fluid is also all the lubing necessary. If the engagement (rear screw on housing) is turned in too much, the problem you described will occur. I wouldn't adjust a Remmy 700 trigger below about 2.5#, or maybe even 3#. Adjust the engagement screw until the action fires, without the trigger being pulled, then back the screw out about 1/2 turn. Do the safety checks. I rap the side of the action sharply with a rubber hammer, as part of my "safety drill."
