I have my new 787 motor and installing the rv now.,I am looking through the mag exhaust opening to find tdc. However once I get the piston to the top I have a question. Is tdc before piston is top or after I get piston to top. It seems I can turn crank about 5 or 10 degrees which will change my rv alignment to set timing. Where should I set rv based on position on mag piston? The beginning or end of tdc of crank rotation? Thanks
