RE: Elec. Advance versus Mech advance
Mechanical advance refers to the method of advance, both use an electronic circuit with a battery...The source coil and mag rotor are both removed either way....
Electronic advance reaches full advance at 4000 rpm, mechanical is linear with throttle movement to 28 degrees advance at wide open throttle..
Hard to tell the difference between the two...
There's a picture of the electronic advance on the Tom Pierce FW190 building thread in another forum here, or search for Tom Pierce....He's using a g62 lite electronic advance engine in his new FW190...
