tryin to break in new engine, ruff idle

Compression test is a good idea too. I looked at the rockers today and the only concern I had was #1 exhaust seemed too loose. I figured it may be a compressed lifter that will fill when the engine runs.

My second concern: the elec choke slowly opens the main carb intake flap fully after a few minutes running. This may sound like a dumb question, but could that be causing a too lean condition, if its fully open?
