Twilight zone adjustment - the reality

My word this is a complicated machine. It is so much more problematic and fussy than an addams family. The one I bought had been extensively maintained and seemed to play ok when I tried it. It has been striped down, had all manner of new parts and boards ...... But now I have lived with it for a few days, the reality of the tz is kicking in.......

Someone had oiled most of the solenoids in my game, or something else had made them horribly sticky. One of the pop bumpers was so bad it even stuck down !!. It has taken ages to strip them down, clean them (I used methylated spirits) .... Now sorted

The ramp mounted ball diverter already had a magnet on it in an attempt to make it more reliable but needed removal and bending to stop it throwing the ball off every fourth go. Now sorted

The ball kick out into the plunger lane needs sorting as about a third bounce straight back. Thinking about this

The clock is paying up about one power on in 4. It already has a rottendog replacement led board, but in am going to treat it to to the German made one that has additional logic boards. I also need to buy a new cog as it is warped, presumably due to heat in the past. I am told that if one opto sensor is missed by the minute or hour mechanisms, it shuts the clock down. Hopefully the extra logic board will end this frailty

The lock is damned unreliable. About two thirds of my lock shots get bounced out, and this is already a difficult shot. These are the clean hits. The slightly messier and slower hits stay in. There are some frightening mods on the web to sort this - brutal bending, drilling out welds .... I need to think a bit about this

Two of the four playfield switches on the mini playfield needed adjustment to register hits. Easily sorted. The mini playfield would not level, so. Had to mess about a bit, remove it, stretch a spring, remove a washer ..... Now sorted. Two coats of wax made a huge difference to the magna flipper performance

The flipper guide holes in the playfield are not symmetrical. So if you use them the flippers hold at different angles.

Does anyone know whether you are meant to have symmetrical flippers on tz ? This game seems very sensitive to flipper setup. Indeed it is very sensitive to everything. But a great game when it works
 
The lock shot is the same on mine, you have to hit it dead on - or a slightly out slow shot will go in, makes it more challenging though!

Agree with Paul , it will be sweet when you get it totally tuned in....the best pin ever made IMO
 
Looking forward to seeing what Lawlor can do with JJP's third title, hopefully he will find the old magic.
 
So nice to play a fully working and a sweet shot machine. When you get it all fully working and tuned in just right there's not many other machines come close.
Think I need to get another and relive the pleasure that's Twilight Zone.
 
You're welcome to try Marks at mine Daz, or hammer the one at Arcade Club next time you're there :)
 
I think any new machine takes a few days to 'settle in'. I don't know why, but that just seems to be my experience

If its still being awkward after a week or so, then start tinkering. But before then, its probably just bitching about its new environment.
 
there are a couple of ways to align the flippers, bent the lugs inwards with the rubber grommets ( reduces travel so smaller ) on the flipper bracket or use a worn coil stop on the side you need more travel.

My clock has a rottendog replacement board and I had all kinds of errors with it when I got mine. Clean the optos, I did and it has not missed a beat since.
The lock shot bounce out and the shooter lane bounce back in the trough are just TZ normal quirks. Fixable but I live with mine as is.
 
To Rudedog1. Thanks for the suggestion. I tried this and it still bounced balls back (but less often) as the kicker rams them out with such force. I think this was problem was caused by me cleaning the solenoid so it operated properly.

I slept on it as my brain tends to figure things overnight. Then it hit me. The kicker arm was smacking the ball square on. So I bent it about 2mm so it now hits more of the side of the ball. This has dramatically reduced the speed the ball gets ejected at. So it is now quieter and shifts the ball correctly. I tested about 20 times with both steel and ceramic and not one missed. So even the little rubber is back on the post now as the steel balls just "loop" out perfectly and directly into the shooter lane without even hitting the post. The power ball might just catch it now and again, but the underside now

This is the simplest and most effective pinball tune I have ever done to cure an irritating fault. If only everything worked out like this!

I don't think they'd be meant to be asymmetrical, but flipper adjustment is a matter of personal preference. I never go by the little guide holes, but sight along the metal rails approaching the flipper. If it's the usual Williams flat rail (parallel to playfield) I project a line through the centres of the screw heads, and place the centre line of the flipper to match. For other arrangements, like Judge Dredd or Taxi, I'd align the upper edge of the flipper rubber with the rail.
