Do you mean like this?

Static compression on this motor was intentionally raised because I 
designed it to run on propane. No real research was done. I didn't know 
enough at that time to think about squish etc.

Bruce, what do you think about these two tradeoffs:

* higher compression (say 9.5:1) and less ignition lead,

* lower compression (say 8.5:1) and more ignition lead.

The two seem to balance in "sign" but I don't know about magnitude. Eg. 
is more ignition lead better than more compression...?
