Messing around with some updates to the 914, no problem finding TDC, but my other timing marks are hard to find. As a means to double check my work, anyone know how many degrees per fan blade? Yes, I've tried Mr Search to no avail.

What system are you running? I take it you have some sort of programmable ignition?
On my SDS I made a mark at 10 degrees BTDC that you saw through the timing hole in the fan shroud. You then started the engine and at idle you set the baseline crank-fire timing with a strobe. After that you use the program to set your timing. Guessing at fan blades is a poor method for setting the baseline. |
