I was getting 40 out of my last 400k, that was from a 170 fill, which it preferred.

My mk2 TX does the same. On taking it apart I found that one of the holes on the cocking arm pivot point had elongated. Solution ? A bit of weld in the hole then drill to the correct size, If i ever get round to it. Alternatively a new cocking assembly.

I got a tatty mk2 TX a few weeks ago. The underleaver has some side play, if i dont concentrate when I return the underleaver to the locked position, it slides sideways and the ball detent doesn't locate, mmm

TX would be my choice. Ive tried to get along at least 3 times now over the years with the PS and ended up selling everyone. Just got anothe TX and its a beauty.
