Not my machine so excuse me if I'm incorrect.
Stators usually only fit one way because of wire routing. If the mounting holes are slotted for adjustment, it's only a small amount of movement. Shouldn't take much trial and error.

If the old stator was fried you could have left the old stator plate in place(or mark it as the manual calls for) and installed the new stator and pick up coil using the the three stator mounting bolts and it still would have been in time. Now you're going to have to use a timing light and preferably an accurate rpm gauge and trial and error in getting it to the 30 degree mark on the flywheel while maintaining 3500 rpms. You have to get the plate at least close enough to run(set the screws in the center of the slot and try that) check where the 30 degree mark is in relation to the recoil case pointer. Kill the engine,remove the flywheel and advance or retard the plate until you can get it to the 30 degree mark with the timing light.

So opt question clockwise rotation of the stator will advance timing and counter clock to retard?

Clockwise retards timing,counter clockwise on the plate advances timing.

Ok opt after rereading this thread and retracing my steps I realized I only removed the stator not the stator plate so timing probably not the issue. Having said that it idles perfectly and the trigger coil is actually at .025 by feeler gauge from the magnitude on flywheel should I be thinking about that cam and reconsidering it?

Timing shouldn't be an issue then..Just for grins and giggles,tap the pick up coil bracket lightly inward. Plus check resistance on the white and white/red pick up wires. Should be around 97 ohms. If the p/u coil is within resistance range and closing the gap further doesn't help,then go towards the cam. Ground down cams would usually idle,but spit,cough and back fire through the carb when you gave them any throttle.Very easy to tell if the lobe is the problem.

The trigger is fixed no room to adjust and can I test the resistance at the Cdi if so its 137
