Hmm....Sounds like you need 10% nitro. With the O.S. LA engines, the break-in isn't as crucial as it is with the old steel cylinders and pistons...the new O.S. engines are all aluminum. Don't get me wrong, though. Breaking in your engine will give it a better and longer life. It sounds as though your equipment is OK, but you'll have better luck with some knowledge and experience to go along withyour stuff.... Do you have a hobby shop nearby? If your engine won't start with just flips, perhaps you hobby shop's electric starter will do the trick They will probably be more than happy to help out. Good luck, Andrew
