I have a run of the mill cheap 66cc happy time engine. The original magneto has been removed and am going to install a hall effect (Home brew) ignition. It will have manual adv. retard. I was just looking for the standard Deg. of ignition for a starting point. I was going to start with 22 Deg BTDC but just wanted to know what the off the shelf setting is.
