Cruising at 3200 RPM, then drops to 800 RPM
Two weeks ago the starboard engine would not start, had been hard to start for a few months. I replaced the spark plugs, wires, cap and rotor, then adjusted the choke. Now when I am out on plane, about 5 mins. later the RPMs drop from 3,200 to 800 and you can smell gas out the exhaust. I put the engine in neutral, revs up fine, and then put back in gear. A few mins later same issue with the RPM?s dropping from 3,200 to 800 and you can smell gas from the exhaust. The engine is a 2004 5.7 Crusader with a 4 Barrel Holley, electronic distributor, about 250 hours. The engine sounds good and runs good at low RPM?s. Oil pressure is about 60, temperature gauge about 140 to 160.
Any recommendations on what would cause the engine all of a sudden to drop to 800PM without moving the throttle?
