Hey y'all.....
I have posted this before and never really got a solution to the "running on" after the ignition is turned off!! This is the 408W stroker with 9.5:1 CR, Windsor Sr. heads, Comp 274H cam, Edelbrock RPM with 750 cfm on top.
I have the base timing at 8-10* with total mechanical of 24*. It idles OK at about 900 RPM at 10*, but seems to want to kick back and wind down backwards(??) when the ignition is shut off......Hissing out of carb while winding down?? The guy that built it says too much base timing will cause this but if I drop it back it idles so rough it damn near shakes the car apart!! Also, I can't tell anything about timing changes with respect to power, but it seems smoother and accelerates smoother with about 10* base timing!!
Any Ideas??
