Maybe it's not getting fuel from jetting, clogged idle circuit, etc, If timing ACTUALLY is at TDC that is no-where to be. A stocker you should have at least 10BTC and with any sort of "hot cam" 15 and somtimes more "Looking at the rotor" is not setting the timing. Either static time it or run on the starter just long enough to flash it a couple times and see where it actually is
