i wasn't as much worried about the main as i am the pilot. i haven't ever really messed with pilot or airscrew so i don;t know how to tell if it is right or not. i can't beleive he would have that jetting in there if it wasn't close but i looked at the pilots and they seem huge. i don't know if its way to big or not and right now i don;t have spark. i got the motor in and on the 3rd kick it stumbled like it wanted to start and then i pulled plugs and it would spark every 3rd kick or so, and now i have no spark at all. i don;t know if it is something dan did when he had it all apart or what, but when i pulled the motor everything worked fine and now i have no spark. so i need to figure out why i dont; have spark first then work on the jetting, but how can i tell if the pilot is right or not?
