Be cautious of using the new replacement recently manufactured condensers , even the supposedly good quality BOSCH brand ones don't last that long in service. As a general rule they should be around .025uF capacity. I sometimes see the old condenser testing sets at swap meets . The condenser is dealing with the primary low voltage circuit but from memory the primary voltage kick back can be as high as 300 Volts across the condensor, this is something to do with the collapsing field across the primary windings in the coil collapsing at a faster rate than when the field is growing .
