not sure ether, timing light on top cylinder, idle adjustment screw moves idle timing, mines turned in almost all the way, idles all day, not worried about idle timing, just smooth idle, been told not to mess with max advance screw, pre-set at factory
Some want to argue on this topic.-----Sorry-----You check maximum timing which is set at the factory for the life of the motor !-------No such thing as base timing on this motor.-----Idle timing is the point where throttle plates open for proper acceleration.------Where the engines idles smoothly the timing does not matter.-----NOTE----This is not the same timing process as you would find on a 283 small block chevy.----Read the manual.----Read it again !
I see you don’t have a manual or if you do your not able to read. Your about as stupid as a man can get. I QUOTE.
