I've recently bought a SAITO FG-21 as my first gas engine and read the instructions meticulously. Then I was very excited to have it start up and everything first go! Did my break-in and everything (never flown)! Only to accidently noticed I have ran in using the incorrect oil ratio T_T. I ran it in with a 40:1 as oppose to the 20:1 indicated by the manual.

My question is, how stuff is my engine? Is there anything I can do to "fix it"? Or just keep flying it until it gives up and get a new one?

Thanks in advance
