It's looking like I might need to put a new coil into a pop number and a slingshot (weak response from both). Does anybody know of any good videos or links to pages that could help me with this? I'll take it apart and try and fix it myself, but I think it might be nice to have some info on it first since I've never done it before.

Thanks!

LTG, I was looking at that while I had the PF raised. The rod from the bumper skirt was a little dirty so I might try and clean that off and realign it and see how it works. When the coil fires it doesn't sound as loud as the other 3 either. That's another thing I'm seeing.

As far as the slingshot goes, one of the prior owners of my machine must have had issues with the slingshot coil because, from what I can tell, they removed the knocker coil and used that for the slingshot. So it's power too, is drastically less than the other slingshot.

I'll see how the readjusting of the pop bumper goes, but coil replacement is still something I'll need to tackle in the future.
