Re: Engine wont turn now
If you have Fuel, Good Compression, Spark at CORRECT timing, the engine will at least try to start unless it is getting way to much fuel and just fuel fouling the plug.
Sounds to me you have overlooked something very simple probably or you've had a failure somewhere, possible sheared crank key, which has the timing all wrong, if you have fuel, compression and spark it will at least try to start unless timing is off.
best wishes, dont give up.
