Where should the timing be set to at idle? How many lines from TDC and should it be advanced or retarded?
Should I set the timing at idle or does it get set by simply pulling over the motor and adjusting it?
Thanks for the help

Anyone have any idea how mercury's are supposed to be timed? Im talking just at idle (with the screw) not the flywheel.
