O.K I just bought a 2008 Roketa Bali and after a day it wouldn't start. I jumped on here and read one of the comments about vac lines and also KEEPING A FULL TANK OF GAS!! This was the KEY answer! I kept disconnecting all of the vac lines thinking it had to be the problem because I had a 1/2 of tank. After hours then days I filled up the gas tank and it started on the first try! I don't know why it can not go past 1/2 of a tank but this was the problem all along! So thanks to the anonymous poster who suggested this! And anyone who is having this problem don't be stubborn like me. Fill up your gas tank you might be as lucky as I was.
