Just some advice for anyone using adjustables - get them tight! This was the first time I've used them, and thinking they might be fragile, I didn't tighten them as much as I should have. Luckily I wasn't too far from home when they loosened up. I was about 3 blocks from the house when I heard a loud ticking noise. Thought it was the engine, but pulled the front pushrod cover off and found it was very loose. Checked the pushrod to make sure it wasn't bent and everything looked good. Hopefully it didn't hurt anything else. Anyone else have this happen?
