 25215 forum posts 3105 photos 1 articles | Finally got round to reading about this engine in issue 4372 and noticed a couple of issues with the drawings.
Fig 9. The 4.5mm dimension is given against the length of the lower liner but should be the width of the central band.
Fig 14. There are no lenths given except the counterbored hole, should be about another 5 before the part can be made. Also ther lift of the cam is not given, just the duration.
Apart from that nice drawings.

These plugs are UNEF threadform, in the UK builders may take this as being an ME thread which is 55deg not the 60deg of UNEF.
