Back when I ran my small boat with a 2 cycle engine, at the end of the season, I would dump the 2-cycle gag mix into the bird, gobbled it up, spit it out, and never made a peep.
Whether or not it will clean anything out, it won't hurt a thing. If someone could explain how a little extra lubricant in the firing chamber causes porblems, I like to hear what problems it would create.
The only problem I see would that continous operation with such a mix would foul the plugs. However, I doubt that an occasional drink would foul the plugs. You know, I might give it a shot because it won't hurt anything, and it might be an excellent way to clean the firing chamber and the area inside of the valves.
What the heck! I'll take a stab at it this spring. It's a Pontiac engine. You think that a short term oil mix in the fuel will hurt anthying? If you want to take chances, use some upper engine cleaner, stuff designed for cleaning out the firing chambers. There are countless cases whereby the product caused hydolock, a deadly condition for an engine.
