David, with all due respect, at the time you adjusted the valve you
should/could have noticed the problem. I had a similar experience with one
of my Landies, and at the point where I noticed my .010" feeler gauge
SIDEWAYs wasn't enough, I caught on that the fully compressed spring with
the loose valve adjuster was likely the culprit.
You have my sympathies up to that point, but after?..............
So, what was the cause..... new valve job with dem fancy bronze
guides? as was my case. Did you bend a pushrod too? as i did.
