We did a compression test, 30-30-35 on the front rotar, and 50-50-60 on the back rotar. We put some marvel mystery oil in the carb to see if it would brake up some of the carbon in the engine. I was turning it over and heard a click. The engine just stopped turning over. One of the coils was sparking blue, then after that I heard the click. Can anybody tell me what happend?
Thanks, Josh.

 

Mine just did the same thing, maybe. Did you lose power and then it came back a little bit later?

That's what mine did, and it ended up being the connectors that go on to the battery were loose, and all the amps it was pulling at once just killed it. That, and it had a bad connection and it was sparking enough to shoot a chunk of lead out of the connector. Check all your connections and grounds.
