93 yamaha C40plrr 2 cylinder

Hi Gang...Does anyone know the factory reccomended rpm range of this motor...have seen 4500/5500..& 5000...and the number of poles on ignition system...trying to prop this thing and getting numbers from tach at wot, i dont trust...verified idle of 1200..(ie inductive pick up from hz reading on multi meter..& 2400~2= 1200 with inductive pick up with timimg light) I believe this is a wasted spark ignition..hence the 2400 reading with timing light..thanks for any &all input...
