Wait.... 86 degrees (before) TDC (top dead center) isn't
"when the piston is at the bottom of the cylinder" (BDC).
Instead, it's slightly after half-way up, when the crank is
at right angles to piston travel.
Perhaps a (chemical?) reaction is occurring that requires a
spark and /a delay/ -- to give actual detonation near TDC ???
