Bumping this thread.

Rusty and I are working on this engine together. There are no instructions provided in the box or on Mittlemotor’s website (at least none that I could find). I bought the distributor from Mittlemotor and when we asked for initial setup help we were told to contact TRE (I’m guessing they’re the Mittlemotor distributor on the US). Dave at TRE was helpful in getting the distributor set up for initial running even though I didn’t buy it from him.

On initial setup, we wired everything up and set the rotor to point directly at number 1 upper spark plug on the cap with the engine at TDC (with Dave’s help). I also found a twin plug distributor cap wiring diagram on the internet and used that to make sure the plugs were wired in the correct order. These distributors are sensitive to low voltage (obviously being electronic) so once we had a fully charged battery we were able to get the engine started.

The confusion I have is, the distributor is timed via the app by setting the advance curve electronically. It isn’t timed by turning the distributor like a conventional point type. There isn’t a lot of info on how best to optimize the distributor for various engines and that’s what I’m looking for.

If anyone has experience tuning this twin plug distributor or the 123.Ignition equivalent I’d appreciate any insight.
