A few months ago I purchased a Westinghouse W9500 dual fuel generator. Today I had the plug out to get a part number (to replace the Torch brand with something decent) and I had a look inside the cylinder with a bore scope. I found the top of the piston covered in a fairly thick layer of gooey carbon which surprised me given the engine only has about 3 hours on it. I've taken a look in other OPE engines with substantially more hours on them, and didn't find that amount of deposits on the piston.
I've run the engine primarily on ethanol free gasoline. Is there any benefit to running on propane as it pertains to engine cleanliness / deposit formation?
I use the generator to make my welder portable for projects around the house. The amount I use it makes a cost comparison between the two fuels inconsequential. Curious if one fuel were better than another for engine longevity and why.
