Very Nice Job Doug T
I ´ve benn following your posts all the time.
I try to use a brand new pro spark i storaged for 3 years in my shop. Now bolted in a ryobi and in a new sukhoi 72"WS went to the field, the system was Ok and the spark at home was big and blue, once at the field I connected the battery, fueled the engine and the spark gone away, it never spark again.
I don´t know what could happen, if the coil blew up, the hall sensor suffered something in the surface, the circuitry failed..I don´t know what could happen, from one moment to another, without use...it just died.

In scratch built ignition formums a lot of guys told me that the tim 6 is not suitable for our gassers and they have a lot of troubles with the coils..how are you dealing with that???

Hope you can tell.
