New motor backfiring through carb

Are you sure you set it back on the firing stroke?.....if it popping back thru the carb is usually a good sign that it is 180 out.

If it was 180 degrees out then wouldn’t one of the lines not be lining up. I drew one line at 12 o’clock and another at 3. If it was 180 out wouldn’t the one at 3 be at 9 o’clock?
