I would check for vacuum leaks as well.
As for timing, I recently had a rough running/poor acceleration issue that came out of nowhere. Definitely “seemed” like timing, but I explored a few other theories first. Advancing the timing (just by ear) cleaned it right up.
All I can figure is that the clamp allowed the distributor to slip. But it certainly didn’t seem loose. The octane adjuster bolt was plenty snug as well.
