Anybody want to take a crack at it? (If you don't know for what BTDC is an acronym, don't bother trying to answer.)
My bike's points open at 0.8 mm BTDC, and I want to measure that with a degree wheel and strobe light. I trust dymanic timing before static, because the points are at the end of a four-gear drive train. Lash, you know.
If anyone knows the formula, or can tell me where to find it, please let me know. Thanks.
