History – 3 years ago. I inherited a Lund/Evinrude fishing/run-a-bout from a family member.
2 years ago - The boat started, ran for 15 seconds, then died (like someone turned the key off). Tried restarting with no results - Sometimes the engine would run and I would give it throttle. Engine would purr nicely for a few seconds, then die like the key was turned off. I brought the boat home and cleaned what I thought was a significant amount of oil out of the carbs after removing the screws to the float bowl. I took it back down to the lake and it started right up and kept running. It ran great for the season (3-4 months) without any problem. Started right up on each of my 6-10 trips to the lake that summer.
Last summer - Before bringing to the lake I cleaned the carbs of excessive oil in the bowls. I brought to the lake and fired it up, ran for 30 seconds, then dies like the key had been turned off. The engine sounded smooth/good. I tried restarting at the docks for an hour then threw in the towel. I was disgusted and parked it for the remainder of the year.
Two weeks ago – Installed two shut off valves (oil and fuel). My reason for installing valves was that I thought temperature and air pressure could be creating pressure/vacuum problems for oil and fuel tank. Flooding my carbs with too much oil. FYI - When I cut the gas line to install valve it looked like oil had run back into that line.
2 days ago – Cleaned carbs of oil. Tried starting it on muffs. Engine would start, run for 3-10 seconds then die. During a period when the motor was running I squeezed the bulb to see if it would extend, no it did not. I also took off the gas cap. At the end of the day, I drained the carbs of significant gas/oil mix and fired in carb cleaner til the cows came home. Left the air box off and engine cover off to air it out.
Suggestions - This engine has less than 200 hours on it. It was always considered a “hard starter”, but I think it has an “on again-off again” malfunction. Perhaps electrical, coil, short.
Thanks in advance.
