G'day Grumpy,
Yes, I lapped both valves and adjusted valve clearances as diligently as I could, as this is something I felt I had some control over, unlike an over sized bore.
I will listen to the noise again, next time I go up there. (hard to descibe noises in text)
These two rebuilds have given me invaluable experience and in my mind, was not a waste of time. I call it all practice.
I now have two working engines, even though they are less than perfect.
Thanks.[Linked Image]
