Yes.... to properly set the carb/advance timing the ignition timing needs to be set as well.

If you dont have a timing light oyu can usually rent or borrow one from an auto parts store. It's cheap insurance, if your a few degrees overtimed it can cause bad things for your motor. Cheap insurance I'd say.

The numbers that tell you the timming degrees are worn off but the marks are ok question is each mark is equal to 2 degrees is that right
