Alright people, here's what happened to my blower. It turns out there was NO lubrication inside the piston cylinder nor on the piston--dry as the Sahara. It appears to me that Startron dried out my gas-oil blend. Conversely, there were no carbon chunks anywhere on the spark plug/socket, nor in the muffler. This is my "raw data".
I bought a new blower and will only use Startron in my 4-stroke engines. My initial reason for purchasing Startron was to negate any issues that ethanol would have on my equipment. I'm sure we've all seen the photos of gummed-up parts and corroded seals that ethanol can and will cause.
