My Silver Century #WSL 617JJ6 has what appears to be 10:1 fuel mix leaking from the bottom of the exhaust tube. It's not coming out in copious amounts but enough to be noticeable. It started after I ran the engine excessively hot in a barrel not knowing I was supposed to remove the prop. I have not tried to start it since. The engine turns over and still has good compression. I'm thinking the excessive heat may have caused some internal damage allowing the fuel to leak. If so, is this a difficult fix?

Re: Fuel Leakage
This is normal, the 10:1 mix means quite a lot of unburnt oil will go into the exhaust, and result in a dribble from the exhaust. I wouldn’t worry about it.

If like this all is well.

That's it exactly, Thanks!
Re: Fuel Leakage
Yes its partially burnt oil that has not been burnt by the combustion process. All is good.
