Re: 2 cycle or 4 cycle oil
I suspect you paid a four-stroke price for a two-stroke engine unless you got one whale of a deal. For future reference, four stroke engines look just like the engine in your car except it stands on end rather than crosswise like your car. They also have oil in the crankcase, just like your car and as such they have a dipstick. While an oil injected two stroke may have a dipstick, it will be in the oil resevoir which is the plastic tank in which "two-stroke" oil lives. Four stroke engines have a cap on top of the engine in which engine oil is added and there is no separate external resevoir. A major tip off is that four strokes, just like your car have an oil filter which is pretty hard to miss. Two strokes do not have one. Remove the cover from a two stroke engine and the spark plugs are looking at you. On a four stroke they are deeply recessed between what are the camshaft covers. A two stroke head is nearly as flat as a dinner plate because they don't have a camshaft. Lastly, nearly every four stroke on the planel has some words on the cover that reads: Four-Stroke. Armed with this you should be able to figure out what you have. As was pointed out, you really need two manuals -- the Owners Manual, and a Service Manual. Screw up removal of the oil injection system and you will wish you had kept your fingers off of it.
