There have been a number of threads related to ethanol gas left in carburetors. I thought my experiences may benefit someone? Sometime back, we downsized our fishing boat, a 1958 Glaspar Avalon with a 35 HP Evinrude 2 stroke motor, & gave it to my daughter & her husband.

I suggested he drain the carb if it wasn't going to be used within a week or so.

He didn't do that. Commenting that the motor was beginning to "run poorly" he took it to a shop who cleaned, or attempted to clean the carb. The result was that it trolled fine but stumbled & died when given full throttle. The shop tried.

I just ordered a new $400 carb which I will install for him. It just takes a minute or two to drain. I also have used this additive and except for one instance when I forgot to drain, have not had any fuel related problems since ethanol gas was introduced:

You also need to keep tabs on the fuel lines if they are rubber, etc, as they will deteriorate rapidly with the ethanol in them! I would also be concerned with the seals and o rings in the new carb, unless they are made of the new materials some what impervious to the ethanol!

My engine was a 1984 model, so it may have "proper" o rings, etc?

I had a 1964 9.5 HP Evinrude, before ethanol I think, ran it up to as few years ago, no problems. Hopefully hose particles would stay in the filter? I change the hoses about every 5 years or so, just to try to avoid problems.
