Ok so this morning the engine was getting spark just fine and before that was getting good spark all summer as far as we can tell. We've been struggling with carb tuning issues though.
However, this morning the spark got to be virtually non existent. It will typically spark once when you hit the starter button and that's it...sometimes not even once. If I pull the total loss wires apart and touch them together it will spark great over and over. If I loosen the flywheel and spin it by hand it will spark great over and over. However, when it's all buttoned up and the starter is going, the spark is very random and usually only the first time it turns over.
We've even tried a different and pablo says he ran an extra ground from the head to the starter ground strap. The total loss is connected straight to the battery on both positive and negative.
The only things I can still think of that could be wrong are the coil and the starter. Maybe the starter is drawing too much current and the battery can't support a spark too...or the coil is toast.
