Re: 1939 Champion S1E and D1E 1 cylinder motors.

Hotrod,
Thanks the info and your perspective.
Both of my motors have the same Eisemann mags. I believe they both have the synchronized mag/carb controls(my assumption is the syncho control pin on the bottom of the mag plate and the interfacing bkt on the throttle arm perfom that function). Both motors have these parts.
My S1E # is 14486 and my D1E # is 4693. The top shroud on the D1E is mounted by 4 screws.
Both lower units are the same. I believe these are what you consider old style.

I also have a unrestored 1935 Model A #5523 with the cast exhaust housing and the exhaust extension tube that goes down to the cavitation plate. I just had a club member tell me this extension tube was and aftermarket item. I also intend to restore it after doing the 1939’s.
