Like I said, I am trying to get the engine to work at all! If you have any idea why it started and ran yesterday but not today, I'd be very happy if you'd tell me. Because I honestly don't have a clue. Though I am suspecting some kind of problem with air fuel mix. Compression measured to 150psi. Load or no load shouldn't matter, the engine must be able to idle anyway. And no point in trying to tune for specific load when I can't even get the engine to run reliably in any case.
