You took me out of context. Do you work for a newspaper?Hmm, explain. With points on these things, you set these statically at the firing position for a maximum possible advance.
Here is the entire statement.
The OP said he had the points set at 0 deg., which is TDC. With that setting, at idle, engine would run in a retarded condition. Actually would run in a retarded condition thru the rev range unless the Ural points ignition starts to advance as soon as the engine starts to turn so that there is some auto-advance put into the timing at idle.If you have points, you need some advance at idle. Most ignitions run at some amount of advance, ie X deg BTDC. How it is achieved depends on the ignition type.
So, for a Ural with points, I would expect the points at idle to open at around 5 deg BTDC. At idle, any centrifugal advance should not be advancing yet. So, to set the point where the points open at 5 deg BTDC, there is usually a mark on the flywheel that is 5 deg BTDC and identified in some way. On early Hondas, they mark that point with an F to indicate firing and that is the mark one uses to static time the engine.
So, if I read your statement correctly, you are saying that you static time a Ural at maximum advance? That leads me to believe that there is no centrifugal advance on a Ural with points. I struggle with that. First, because it would cause the engine to kick back violently when kick started. Second, It would ping like crazy when under load at mid to low RPM. And lastly, I cannot think of any engine with points that does not have a method to increase the advance with increasing RPM. Before centrifugal advances, the spark was advance manually.
So, please explain how you static time a Ural at full advance and have it run properly. Do you lock the AAU in full advance position and set to a mark on the flywheel?
