The code is small.....very small.
There are no security rules into the code without a *startup unload C* with grounding the scr.
If the magnet is into the neighborhood, the rule didn't work.

The hall need at least 25 degrees BTDC be placed.
The easystart into the untill 1800 rpm need this, the CDI start Point Of Pickup (hall) minus 25 degrees
Normaly a weeteather have a BTDC ignition of 36 till38 degrees.
2 stroke engines need more degrees, 38 + xxx, 4 stroke need less degrees, 38 - xxx

Use a degree wheel to set TDC and BTDC, dont use the flashlight in the first run.
The flashlight was made to controle the CDI if everything works and you will fine tune the engine.

PS, don't use the file I send to you.....there is a mismath in it, I hope I can fix it tomorrow.
