Well, I finally got cooler weather and a day off so I could have a second go at this. I checked all of the things MTD & Tecumseh recommended: Tygon Tube, fresh gas with stabilizer (and Seafoam), oil, intake & cooling fins, fuel filter and finally cooler air temperature. Everything looks good, but I am still getting the bubbles. I did notice that the engine has a slight cough / stutter / sputter thing going on. It only happens occasionally, and I am not sure if it is a misfire, backfire, or pre-detonation, but it seems to coincide with the bubbles. I thought maybe it was forcing air through the venturi into the carb bowel & back up the fuel line, but it I get the bubbles even with the air filter off, so it can't be pressurizing the venture. Maybe it is just shaking the bubbles loose in the fuel filter and allowing them to rise. I have no idea where to go from here.
