Anybody had advanced timing issue with 80 to 83 XT250.  Bike started to kick back when trying to start.  Checked timing

and it is way too far advanced.  Timing is a little over two inches distance on flywheel advanced.  All source coil and pulse

coils check good.  Any possibility CDI unit has just shot craps?  Please let me know if you have seen this issue.  Have 

checked position of crank.  "T" mark lines up when at TDC.

I've had friends with XT250s that would backfire almost every kick, it was an issue with the CDI, check that all the connectors are connected to the correct colors/connected properly, and give them all a good clean. That might help the issue
