Tiger, turning over that engine without a working decompressor will call for a fairly serious effort, and a properly coupled blade plate. Otherwise, unless you are meatier than average in the arms, it will just stop when you get to the first cylinder compression, and you will think there is something wrong with the engine, when there isn't. The decompressor is there for a reason: without it, the engine is much too difficult to turn over. Since your decompressor is not working, and your blade plate is not there to give you a reasonable amount of rotational momentum, it would take an accomplished body-builder to turn the thing over. Just pray it doesn't fire, because with no blade plate, it might break a couple of your fingers on the starter handle when it inevitably kicks back.
