Hi All,

I have an Evinrude 1983, 3Cyl 2stroke 70Hp motor. I purchased the boat and motor 7 months ago and it hasn't missed a beat. I took it out today after 7 weeks in the shed and encounered the following. The motor will start and idle fine, however, when slowly throttled up it will stall. There semed to be some excess fuel aroud the fuel lines in the engine case, so I disconnected the fuel line to use excess fuel in the system. As soon as the fuel hose is disconnected from the engine it will run perfect for a short time. Reconnecting the fuel line results in the same problem. Seems it is getting too much fuel.

Any ideas would be appreciated.

Jeff.

Could possibly be a stuck float or float valve in the carb(s).

explain excess fuel around fuel lines, are the fuel lines leaking, or the carbs overflowing?

KermitV4,
Sounds to me you need to purchase carb kits and clean/rebuild the carbs. I would do this if you haven't never rebuilt them before and and they are pretty easy to do just make sure you don't mess with the linkages and pay attention how stuff comes off to know how to put it back on and make sure you mark the carbs as bottom, middle, and top carb so you put the carbs abck in the same place they came off. This should help you out. Take care, Bob

There was a little fuel pooled in below the carbs, and some on the fuel hoses. I have yet to test where the source of this is.

Back to the problem, another point is, when I did get it to run to full throttle by disconnecting the fuel line from the tank for a bit, it would run great until I shut it off for while, then after restart the problem would reappear.

Thanks for the replies so far everyone.

Sounds like a sticky needle valve inside the carb.
