Boy I just pulled a bonehead move. Freaking old brain got me.  2 hrs of work on a saw for notta. Grrrrrrrrrrr grrrrrrrrr grrrrrrrrr

Tested yellow saw with good spark, but **** bar mount area and cylinder muffler mount issues.  So got the above 4500 in no spark tested out yep no spark. Cant remove coil without pulling plastic fins off the flywheel so I did this on both saws along with recoil pawls.
I went ahead and pulled the yellow saws trigger another name ? not sure and coil to put on as a set.  Somewhere along the line I think I mixed up the coils. Now no spark on the orange saw with good set. I think I put the bad coil back in.
Right now I just want to kick my butt for getting confused and grabbing wrong coil.

Few choice freaking words were said and thought of a shotgun rifle and a 4 wheel drive.   ;D

Hot dang I had took a pic of the good coil and whatever it is called before I pulled them out of the JD. Now as long as I can make out the markings on coil and a little different from other one.

working on pics to see if I can tell.

Yep here is  your sign.   I did it, put the old bad coil back in with the other lead part. I'm such  :P

The good coil in pic has 2 dots to right of the numbers. The bad coil has 1.   ::)

Least I confirmed my dumbazz move and why no spark.

A Country Boy Will Survive.  Glad you got it licked Kevin.  We've all pulled bonehead moves like that...................at least I sure have.
-Aaron

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.
