Glad to hear you got it started. The H's and M's were hard to start in my experience due to the 6v system. My Farmall H has issues cranking when it gets cold out, and if it doesn't crank fast enough, the extra compression I have due to putting in high altitude pistons makes it stop dead in its tracks when it tries to fire. I get tons of power from the new pistons, but it does make starting harder. I'm contemplating converting mine to a 12v system to help out with that.
