We have the prop drives that are designed to solve ALL the timing issues. The Over Timed issue and between the Cylinders in all series FG19-FG33_FG60 and FG84/90. The FG73 is just over timed. The timing between cylinders is correct..
You can find all on the CH Site.

I see the step-by-step instructions, thanks! It would be great to see short video of the process :-)

Yes I make them. Now the FG75 will fit the FA325 . I made it to be compatible.

The on-board telemetry sensors for temps (1 per cylinder) showed only a deviation of <2degrees C on the ground (idle) and in flight for (mid-range)..! Seems like the careful running-in (see previous posts) paid dividents.. Temp range was between 80-90C on the ground.

Note: readings are taken between the fins just below the spark plug, on the rear side (to avoid speed/cooling effect of oncoming airflow). In reality, CHTs will be 30-40C higher on near the top of the combustion chamber.

A +20C difference between Nos 2&3 and No.1 (top cylinder) was recorder after prolonged mid/high throttle settings in the air. This was expected due to the relief airflow arrangement in the cowl (louvres only on the bottom side for scale reasons suck more cooling air around the bottom cylinders...).

A Happy customer!
