Here's the slow mo version. Guess they are firing it at TDC because it's running so slow...or maybe to keep thing together LOL still way cool. Wish it was even a slow-"er"-mo, so you could see the first kernel of flame.
Running a little rough! Two misses in the first minute that I saw. And it's definitely firing right at TDC. You see that spark light up right as the piston kisses the top.
