I am sending some pictures of the controls for shifting and speed. The Seloc manual is very lacking on description of the timing of engine. I have changed some parts in the ignition, overhauled the carbs and want to make sure everything is correct. Book calls for measuring 12 degrees before TDC and go rotate engine counter clock wise to 12 degrees measure distance between the 2. Couldn't I just measure TDC with dial indicator at very top of stroke and set pointer there. I have an inductive timing light to determine timing advance. Can someone help with the set of the speed controls adjustments and let me know where they should be set.
