Got the repair kit. MR05 runs smooth and quiet with the T-tech grips and pushrods. Haven't tried the MR03 grips on the MR05 because the cartridges won't seat without pliers. I changed the vice screw to a wingnut style with a little longer screw. Didn't like the little round knob thing. Haven't used the MR05 to tat with yet. Feels pretty good in my hand though.

MR03 doesn't run well at all. Runs inconsistently (fast and slow). Runs very loud (clatters). Had already drilled out the lower bushing before I got the repair kit because the lower pushrod was sticking. Doesn't restart unless I unwind the grip each time I stop. Had to cut the sponge spring in half (relieve pressure) to get the machine to start at all. Sometimes the upper pushrod comes off the swash cam ball thingy.

Ed says he's working on upgrading everything. Hopefully he get's it running smooth, quiet, and consistently. I really like the feel of the linear machine in my hand. I use the Stylus now, but would like a little more power.
