You also have a low comp head, Ruby head would make big difference
I've understood a 1.25 inch SU (which is fitted now) should do fine.....so that's disappointing to say the least... And I've got both Ricardo and Whatmough Hewitt HC heads lying in waiting..... I'll try fiddling. with advance/retard first... but must consult my friendly mechanic as I'm not versed at that.
