Battery freshly charged and tested at my work starter runs just fine could you explain that part a little more

Simple-----I did not know that you had a charged battery that was tested.------Many modern motors need to spin the flywheel at 250 RPM for the magneto to produce a spark.----You have replaced many $$$ parts and some orderly trouble shooting needs to be done on your part.

I know the flywheel is moving at a high rpm what it is spinning at I do not know but the thing I think is doing over 250 rpm

I also don’t know what else to try to trouble shoot I’ve unplugged the kill switch at key and motor I’ve un plugged the tach wire at the motor anymore ideas because I’m completely lost

You have spent big money on parts.----Based on friends suggestions ?-----Time to invest in factory manual and do orderly trouble shooting.-----Assuming your flywheel is spinning fast enough will miss lead you !!

It’s cranking just as good as it did whilst running maybe even Better

Probably 550 in parts

Time to do some orderly trouble shooting.-----New factory parts used?----Or parts from an internet / online seller ?
