Your words about fuel pressure are a concern. For that engine the fuel pressure is spec'd 9-13psig, and the warning I see is any lower or higher can cause problems. Do you have a regulator on the fuel, and have you verified pressure at the engine with a gauge? I'd be adjusting for 11psig, given the spec's.
