340 Chugging instead of Reving

I just brought it to TDC again with my finger over the spark plug hole. Felt the compression and watched as both valves closed and rotor is in #1 position. From there, I rotated the crank 180* and the exhaust was opening, intake was closed, per the picture I posted earlier.

You need to rotate crank 360* after TDC compression stroke to get overlap, or look to #6 for equal overlap when #1 at TDC compression .
