I have this same problem with a CV15T, to the best of my
understanding the gas is leaking through the carburetor...
Although a rebuild kit might fix it, certain parts personnel
recommended I get a new one, which we never got to the
price part but I know they start at 75 dollars and can run
well over 200...
My solution, turn the fuel shut-off petcock to OFF every
single time after the machine is done being used.
One or the other...
