I am trying to make sure this ignition is not smarter than I am. Maybe I am making this too difficult, please see what you think.

I am converting a G26 mag to electronic ignition, as I am sure many have done before me. I have read the instructions that came with the CH Ignition (as well as have worn out the search feature) and may be confusing myself. The included instructions seem to be meant for many applications, and the specific Zenoah instructions are to convert a factory electronic ignition to a CH Ignition.

In a nut shell I have located TDC and both sides of the dead spot. I then centered in the dead spot and took the provided degree wheel and put the "zero" in line with the magnet on the new rotor. If I understand correctly, all I have to do it locate the sensor, 30 degrees before TDC. This would mean if I locate the "0" at the magnet location on the rotor, I need to locate the sensor in it's slotted bracket, 30 degrees to the left on the degree wheel when viewing the engine from the back. Seems simple enough.

What has me second guessing, is that the sensor is slid all the way to the right in the slotted bracket. Which means if I needed less than 30 degrees before TDC, I would have no more adjustment.

Can anyone confirm I know what I am talking about or that I am way off base?? How close is close enough? Once I mount the moter back on the plane it seems about impossible to adjust accurately, so I am trying to get it right the first time.

Maybe it's late or the fact I have never had to set timing on one of these . . . .

Thanks guys
