As for it slowing down, does it only do it at the end of the record, or the beginning? Does the slowdown depend on how loud the particular tracks are that are playing? Are you giving it a full winding?
I have an old Silvertone portable that has only a single spring, looks like yours does too. Mine can slow down if I use a loud needle or on especially loud parts... the resistance on loud parts can sometimes audibly slow the record down, so I use a soft needle, always give it a full wind, and made sure it's all clean and lubed. This cheap Silvertone was designed to barely get thru one record and no more.
Normally lateral-cut reproducers like yours would not have a spring or anything to reduce the weight, but you might want to try to add a counterweight to the elbow the soundbox is attached to, to reduce the pressure on the record. I.e. the soundbox is pivoting where those two tubes connect, you could attach a stiff wire with weight on the end of it. The weight would counteract the weight of the soundbox. Technically the weight of the soundbox is what is *supposed* to be on the record for the needle to track the record as designed, but I think you can experiment with counterweights a little and add just enough to eliminate that slowdown... as long as everything else has been eliminated (you said you replaced the spring). You could put the rod with the weight(s) on it temporarily with rubber bands or whatever so you could play around with it and not make permanent modifications. I'm not talking about removing a ton of weight where you would start getting mistracking or anything like that, just a small % of the weight and see if it might help.
