Thanks Vid, I just rebuilt the flippers on my DE Time Machine and they are super crisp, and the ball flies off them. I do need to go back and readjust my EOS switch, as it seemed that when I was getting the 1/8" EOS gap, I was getting very little positive contact at the closed state.

But my question is about one of my flippers refusing to stay in position. The right flipper, within a few games as crept up clockwise. I have it tightened up so hard I am worried about breaking my allen key. Any ideas ? It is almost like the momentum of the flip is moving it up. Maybe if I redo the EOS gap it will help, or maybe I should take the flipper off and rough up the shaft where it is attached to the pawl mechanism ?

Anyway thanks again for a source of advice and info.

Thanks Vid
I'll check the tension bolt. the flippers are original (even got the original Time Generator decal on them) and the right one was working well before.

Cheers Vid, I took it off and unscrewed the bolt right out, cleaned and threaded right in then started again and now it is locking properly.

So there's a couple of other things that are quite different since I rebuilt and I don't know if it is adjustments, or just differences in sizes between the original and the kit.

The backhand shots to the ramps used to be very reliable shots. Now they just don't seem to be achievable and my head hurts from trying to work out the physics! Do you think it would be different size in the coil stop limiting the rotation, or the EOS opening too late and the power staying strong through out the stroke ?

Also, I used to get the occasional airball off the posts on the playfield, but now the ball is going up the ramps and sometimes leaping the side of the ramp - I had one ball jump the right ramp and get stuck above the ramp plastic and under the glass.
