No disrespect taken Max. I am curious how turning the motor over with the plug not fitted can kill your coil? Not that I'm doubting you I'm just always open to learning new things.
*sigh* hangs head in shame. After re adjusting the coil clearance it still did not fire. So the engine got used as batting practice. Dumb? yeah but at least I feel better.
Pritty much what The Shard said... A really easy to put it....
If the spark has no where to go,where does it go..... generally the negitave terminal on the coil, arching internally or externally
u might be lucky...itmight of been externally check to see if there are any markson the coil from the base of the lead, if so clean it, and recheck spark.
