I have a small block chevy 350 with a Summit electronic Dist with mechanical advance and a MSD 6AL, Analog CD ignition box
I have been having a issue with trying to time this in that it will run but with a timing light hooked up it shows about 40 degrees advanced at idle even after setting the up with a the #1 piston at tdc and the rotor pointing at #1 .
the mechanical advance seems to be fine , With the timing light hooked up the flash of the light seems to skip once in a while and can be felt in the idle , When driving it has just died and is hard to get restarted , it cranks but acts like there is no spark , on hard acceleration around 4500 rpm in any gear it seems to sputter but keeps pulling .
In the Distributer the magnetic pickup visually looks ok but (I am not sure i have the correct name for this) but the Trigger for with for the pickup is heavly corroded . Can this corrosion be causing this ? is there supposed to be a set clearance for trigger and pickup ?
thanks for any help i can get .
