OK! So last question I asked you guys helped me so well i was shocked. I have another question. My NGG Williams have bottom left and top right flipper dragging horribly. The left is ok for a few minutes but after prolonged play it starts to return super super slow and eventually wont even drop back unless a ball sits on it. Top right is same deal except has progressed to not working at the start of the game rather then slow decline.

I've done a bunch of reading on here and online but lost a few of the threads I saw.

Maybe it's just a coil sleeve and I can take apart everything and just replace that?

Or should I just replace the entire assembly?

Also should I just replace the bottom right even tho its fine since ill be down there anyway?

I also read that I should be looking for like a new age updated flipper with better connections and tighter springs? Where can I find that / whats the name for it? (Flipper v2? lol)

Also, Solder wick or pump? It'll be my first time using either so a little nervous but spent many hours as a young'n soldering boards in school so not worried about that part.

Thoughts please??

Alright just giving an update. I took the flippers apart and I noticed the arms looks fine (no rubbing) and the switches werent pitted and messed up either. I think I was just the bushing and the flipper stem needing to be cleaned off. But since I had everything apart any way I replaced it all. It works perfect. Any on who is scared of doing flipper rebuild- Dont be. Super easy. Pull the big wires off since they are snap ons, Solder the switch off and your good to go. I read a forum on here about how to rebuild them about 6 times then when I went to do it and pull the article up my lap top was dead!! Still knocked it out perfect. Just remember the gap you need on flipper and to squeeze your stuff when you tighten it to keep it protruding. (last part is kinda vague because I forgot the names of parts but just look up the insane step by step on this site) Don't be scared! It was all common sense stuff!!!!!!!!!
