You might want to make the capacitor in series with the ignition coil half
(or maybe a quarter) of the size.  That cap sets the amount of energy being
dumped into the primary of the coil (and also the current flow, etc.)  Too
much energy = dead coil.

You might also need to select a different TRIAC.  Essentially, the TSG
trigger circuit is a variant on the standard auto ignition coil driver..
