Apologize if this topic was recently covered, but I did a quick scan and didn't see this specific problem. The Starboard Lehman 120 (1978) is very hard to start after secondary Racor filter change and bowl clean out, requiring mid-3/4 throttle to catch. I did the normal priming at the injection pump bleed screws to bleed air from the system, at least enough to get her started. I'm now wondering if there is another step required to purge additional air that might be affecting proper engine fuel system operation, maybe on the primary filers? I've never had to do this in the past, and never on the (much easier to deal with) Port engine. Another symptom is that once started, the engine dies when pulled back to about 650 or so for idle, or when put in gear. Thanks for any advice.
