LOL. I know the feeling. Been since high school since I welded anything. And learned all over again on the YD. I know for a fact that I have still a few shady welds on it. most of them have been fix because they did break. But never fails, it's after my son comes in, and I hear a clanking, or shaking noise. I ask him the same question. But his answer is, Ya, but it wasn't getting any louder. Or my favorite... Ya, but the noise stop when I stopped.
But I know what I've welded and find the issue pretty fast.
So far everything I have fix, has been solid. So tells me I'm getting better.
Kids are getting more ballsy with it thou. Think I need to mow and clear out a small circle track for them on some lvl ground. Seems like every time we go out, the engine revs higher every time.
