Don't know where to start with your post. Sentences help a reader to better understand the post. Did you mess with the timing at all when doing the piston and rings? Do you have a bright blue spark or yellow? Is it flooding out?

I hate to be the grammar nazi, but I agree. Please use punctuation and we could understand the problem better than that long run-on sentence.

Hi sorry about that . Yes there is a bright blue spark . My son says he didn't mess with the timing . I can't understand how it was running for a few hours then just cut out and would Not start up again .
