So, here we go, don't laugh (too much):
I accidentally ran the tank dry on the Jammie Dodger last week and i'm afraid I sucked ... something ... into the fuel system. It had the original Evinrude metal tank complete with required bits of rust and such. One of these said bits must have been sucked into the line during the initial re-pump of the bulb... Got her home (after much rowing and the help of a friendly boater), filled her up, ran her again the next day and she was fine for about 20 minutes. Then she died out; fuel starvation. I pumped her up again and she ran fine the rest of the day.
Next day, on a cruise with the wife, there were all kinds of delivery issues. I would run WOT for about 10 seconds and the motor would die. Slow speeds were fine, but nothing above 1/2 throttle.
Thinking back on the tank age, I went out and bought a new 6 gallon tank, new tank fitting, new bulb/hose assembly. Put her back in the water and she Ran good for a few minutes at WOT then died. The new line is a larger diamater, so I think I am getting more fuel to the bowls before they run dry. But they are still running dry.
So, next day, off comes the fuel filter for inspection. It was pretty clean really. I cleaned it out anyway, replaced the line from the fuel fitting to the filter and then ran her again. Much better performance now. I can run 3/4 throttle all I want. But, again, WOT drains the bowls. Only thing I can think of at this point is the fuel fitting from the bulb line to the filter feed. The filter just wasn't dirty enough to have allowed anything to pass through to the carbs (I think). The engine is a Johnson 40 VRO. Runs great, and I don't think the carbs are the culprit, as it runs fine when WOT, until the bowls drain.
Could there be something obstructing the little fitting at the engine cover? Its just not that big, so that my next best guess. Any other advice is welcome!
