Re: 1st build and a couple of questions
Are you using the kit supplied chain? They are notorious for poor quality. My first kit chain actually had a twist in it. It was easy to see and although it seemed to run true it certainly looked scary as it moved through the sprockets. I replaced it within the first few days with a good quality #41 chain. I've also seen the kit chains with tight spots in them, rollers not rolling, which gave the appearance of loosening then tightening. Before you do to much modifying I'd suggest replacing the 415 kit chain with #41. It's available at Grainer, Tractor Supply and even Ace Hardware carries it and master links. Hope this helps you out.
