Need help with 16hp cast iron Briggs&Stratton timing setup.

[90cummins]

I have a cast iron Briggs&Stratton 16 hp model 325431-0135-03
I am rebuilding it with a new OEM +0.010 piston and rod for my log splitter.
I completely disassembled the engine to the bare block and removed the breaker points push rod and installed a magnetron ignition.
The Briggs manual does not give a specification or procedure to precisely check/set the timing based on piston position.
Does anyone know how many degrees btdc it should fire or a piston position??

Thank 90cummins

Timing is set by the flywheel. There should be a key for flywheel. That's all that needs to be done. Good luck with the project.
