I'm running more than 16* with my AFR's.. you can run more initial timing with Alum. heads.. I was running 14*, tweaked the timing to who knows where.. 19* or so... and picked up 10RWHP and 10RWTQ, with no detonation and air temp at 87*.. I would think your fuel pressure is way to low also... oh yeah, I run 89 octane gas in mine.. in the winter at least and I have a little more compression due to 58cc heads ;-)
