I was saving this engine for another project but my 98 500 decided to crack a piston so I bolted the 90 engine in the 98.
When I went to kick it for the first time and it kicked back and damn near broke my foot,my foot was purple for a week.Next kick it did the same thing.
So I guess I figured out why the cases were broken when I got it.
So,I swapped out the 90 stator and flywheel for the ignition off the 98 and it fired up first kick and is running very well.
Anyway's,my question is,What could be wrong with the 90 ignition system?
