Doing the once over before the national, checking the compression the readings were 1=170 2=140 3=130 4=170 I'm thinking slight leak between 2&3, any other thoughts on these figures welcomed!

Hmm -well not ideal, but not really bad enough to warrant pulling the head. A 'slight' leak will quickly become a bigger leak - so why not take it out and give it a good hammering - then measure again to see if it's worse! Meantime - worth checking the valve gaps are ok and the exhausts are not closing up.

Hmm, good thought on checking the clearances, thanks!
