Earlier this year I was having a problem starting my snow thrower and then to keeping it running. I had already changed the spark plug, cleaned the air filter and carburetor. To start I had to use a paint stripper heater to warm the cyliner head. To keep it running I had to run at half or at full throttle. Surely there isn't much to a two stroke single banger that can go wrong. Anyway a month ago I had a similar problem with my weed whacker. On this one I even stripped and rebuilt the engine. Didn't improve much. The only variable left was the two stroke engine oil ratio. Sure enough. In my effort to minimise polluting the atmosphere I had added engine oil on the thin side and this must have caused the engine to seize somewhat. A richer oil to gas ratio fixed the problem. Its late October and we already have our first snowfall. Keep this oil-fuel mixture ratio in mind if you have trouble with a two stroke engine. A little rich on the oil might improve your engine reliability.
