It looklikes the scr (BT151) live his own life, try a other one.
I know from others, if the Voltgae from the HV-coil is to high, the BT151 can't handle it.
The high Voltage can only when the CDI is running in low RPM - test 300 RPM.
I'll change the low-test in the program to 1000 rpm, maybe this will safe the scr.
Others use a FET or a IGBT, I don't have problems wih the BT151.
IGBT - IRG4BC30K0 or some other N-channel IGBT
