40 degrees initial!

It should spark knock like a beeotch with that much initial timing. No way would I run it that high....and I would double and triple check everything regarding the timing. I know you say you have, but it sounds like something's not right there.
Thanks Rusty. I never drove it like that, obviously. Just idle and there was no spark knock at all. Maybe my springs are so light I'm drawing mechanical at 1000 RPM but I just can't believe that. I use two blue light springs. I'll double check and make sure my springs didn't bust or come off. But I really doubt that happened
