Good going! EOC has tremendous potential to raise your overall FE. It's especially helpful on a cold engine, as it runs a very rich mixture until it comes up to the required temperature.

You mentioned clutch starting - hopefully you've seen the recommendation somewhere, to clutch start in 5th gear, even if you'll be putting it into another gear once started. That spins the engine a bit slower, with less jolt to the entire drivetrain. It's enough to start the engine unless possibly you're going very slow, like under 20 mph.
