working out compression ratios
#13
I hadn't fully appreciated the effect of the boring process and oversize pistons. Having worked out the LC head (an early one with priming brass bolts) I get about 5.2, (its like filling up a swimming pool by comparison!) which I suppose is the effect of the larger +040 cylinder being compressed into the same size head.

Btw, how are LC water outlet repair doobries affixed to the head, assuming they create a whole new mating surface? If I have a little cavity in the original mating face on the iron head, can I just fix it with JBweld or will it not last?
