Street Demon tuning experience
I have the 8 in Hg spring in for the metering rods. I looked for a 10, but haven't seen one.
I haven't thought to mess with the timing to adjust it yet. I have it set at 20 degrees BTDC at idle and around 36 risk mechanical (and then ported vacuum advance on that). My idle screws are nearly all in. I finally saw them lean the mixture up all in, but the car still ran. I am currently about a quarter turn out.
My idle is around 750 RPM. I'll spend some time this weekend adjusting timing and idle speeds and see if I can get the idle screws to work more and see where I can go from there.
Thanks!
