Thanks fellas.  Yes I had previously took the engine out to rebuild the top end well I sent the jug to a guy who destroyed it. But before all that I completely repainted the frame reinstalled the engine and had a heck of a spark. On the painted frame. Now the engine was leaking around the head and had no compression.  I took the engine back out. Had to buy another jug cause the previous one was destroyed, took to a reputable machine shop. Got it all fixed. Engine is ready. Heres the crazy part. Reinstalled the engine just like the time before ( mind you I changed nothing) and now I have no spark.  If it was a grounding issue why did it fire before and not now.
