I finally had to flatten the end of each pin to get it to grip and stay in place, but I still have trouble with throwing the track at the left idler, and you can still hear them popping and clicking when they run. If I have to I'll go through them link by link, but I was hoping not to have to do that. I'm wondering if something went wrong during casting these inks, like maybe cooling to fast or too slow, or something like that. I can't think of any other reason for the holes to be too big. It's been suggested to try adding or subtracting a link, but with these KT tracks it's not that simple. You have to add or subtract TWO links at a time because of the design, and that makes a huge difference. I think it was Strato50 that suggested stripping the tracks of paint to see if that helps, so I might do that first, but you know how it is trying to find the time. That's one of the reasons that I sometimes hesitate to ask for help here, because the guys always try to be helpful and have great ideas, but then if my lazy butt doesn't get to it in a reasonable amount of time I feel bad about it. I'm also tempted to just buy new tracks, but that would be a very expensive fix, and I'd much rather spend that coin to upgrade to a hobby grade Tx/Rx. But I'll keep plugging at it and I'm sure I'll figure it out eventually. After what you had to say, Dan, I think I might try setting it on blocks and just running it for a half hour or so to see if that makes any improvement.
