Is all spark created equally?

Recommended Posts

Hello, I recently bought a Simplicity 725 with a 23D replacement engine. I thought is was seized, but turned out the backing plate behind the flywheel was never bolted down and the armature slipped down and was wedged against the flywheel. I have read my Briggs manual, gapped the points, cleaned the armature, flywheel magnets, done the proper air gap between the magnets and my three-legged armature, have a known good spark plug, and I finally got spark. The only thing I didn't have was a flywheel retainer key (yet anyway). I bolted down the flywheel and had great spark. Tried to fire the engine, still great spark, but it wouldn't run. Finally, to my question, if I have spark, does that mean my timing is correct, or could my timing still be off? I will be getting a retainer flywheel key soon and know I really can't expect to run anything until I get this part. Thanks for your advice or suggestion as to what could be the problem. By the way, I did disassemble, clean and inspect the carb and it was getting fuel, but just wouldn't run.
