It turns over fine, i'll explain what happened, last time I ran it is when I figured out the backfip thing and ended up stopping the flip upside down in mid flight and landed upside down, cracked top fins off the head, cracked the fuel tank, but it started right up after that and was OK? Then a few days later I went to run it with my kids and would not start, thought it was the tank, got used tank and tried again but seems like it wants to start but won't, glow plug ok, getting fuel? Maybe it did something internal or to the carb, also broke the engine mount too when this all happened?
I've been thru all the usual things? Just lost now?
