Hi Guys
Just an up date on the saga
Where I last left you, on the ever continuous story of the mysterious ?tap?, seemingly from one of the valves, that occurred when I rotated the re-built engine over, either with kick start or in 4th gear & turning the back wheel
I had screwed down the tappets so they connected with the valve heads to eliminate excessive clearance some of the guys had suggested may have been the problem, and still had the mysterious tap ? so it was not the tappets and clearances ? I thought
Feeling positively dejected, and visualising the engine casings coming back off, I went down the pub, and consoled myself with a few beers.
Got up next morning, said try one last time and went and turned the engine over with the back wheel whilst in 4th gear ? tap still there
I thought I would just re-check the tappets were fully turned down, and found a bit of clearance on the LHS inlet valve ? screwed it down
The ?tap? was now only one in eight valve openings instead of one in 4
Checked again and found I could turn the RHS down very slightly
- noise gone completely
I reset the tappets to correct clearance ? no noise!
Engine completed
It turned over 2nd kick, and runs beautifully ? sounds great!!!!!!!!!!!!
The engine re-build included a new camshaft, and new cam followers.
The toolmaker from the WSBSAOC that re-built the engine told me that he had had to grind the cam followers to get them to locate in their position. Whether this was part of the problem, or what I do not know
All I can say, is many thanks to all who helped me through this situation
Kindest Regards
