[/quote]What's wrong with HEET? It's just methanol, right? I mix it with glow fuel until I get around 10% oil content then mix the whole shebang with 2 parts gasoline.[/quote]

From the HEET website:

HEET contains special additives and methanol. When HEET is added to the gas tank, it sinks to the bottom and mixes with any water. Since both HEET and water are heavier than gasoline, they go to the bottom of the gas tank. HEET absorbs water and keeps it from freezing, and blocking the flow of gasoline through the gas line and fuel pump. When the vehicle is started, the additives, methanol, water, and gasoline are consumed during combustion inside the engine.

Could those "special additives" have anything to do with the balkiness? The manufacturer says it's OK for four-strokes, but warns against using in two-strokers. John
