If originating via the valve cover vent . . usual suspects are too much engine oil, or excessive piston ring blow-by. Consider experimenting with adding 1 tablespoon (½ ounce) of 2-stroke oil per gallon of gas, unless you are already using 1 ounce per gallon of Seafoam. The supplemental top end oil may, or may not, reduce blow-by.
Material Safety Data Sheet comparisons . . .
Seafoam per MSDS:
Pale Oil 40-60%
Naphtha 25-35%
Isopropyl Alcohol 10-20%
Berryman's B12 per MSDS:
Toluene 40-50%
Acetone 20-30%
Methanol 20-30%
Methyl Ethyl Ketone <5%
Isopropyl Alcohol <5%
2-Butoxyethanol <5%
If origination is unclear, another scenario . . .
