Boat is a '73 23' Seabird with twin Aq130c's and 270T's. Fairly new boat to me. Boat has maybe been run once a year for at least the past 5 years. May have been sitting longer without operation. One engine isn't crazy about starting. It will start and run, but only after 10 different tries including pumping the gas (about 8 'pumps' with the control lever) and intermittent shots of ether. Ether will cause it to start immediately although it may not stay running. When I pull the gas line from the carbs and turn the key, gas pours out. Compression test (dry test and not warmed up) is 155, 160, 160 and 145. If I disconnect the front two spark plug wires and shoot a little ether in (with gas turned off), engine runs' 'til out of ether. Same if I switch to rear two plug wires removed. Once it is actually running on gas at idle, if I pull the spark plug wire from cylinder 1 or 2, there is a major stumble. If I pull the spark plug wire from 3 or 4, no real difference in engine smoothness. About 350 hours on very stock engine (conventional carbs, coil, distributor, etc ...). These symptoms seem somewhat anomalous to me. Any direction or ideas on how to diagnose/repair/correct? Thanks, Hans
