1. FUEL in Bowl will NOT deplete in 10 to 15 seconds, so that is NOT your problem for running 5 seconds and stopping.
2. IF you still think it is, just spray B-12 into the intake when it starts to die. IF it IS fuel starvation then it will stay running. If it does NOT then fuel is not the problem
3. Did you replace the Condensor? A bad condenser will cause your type problem
4. Are you positive all 16 pinholes in the Needle fuel jet are completely open? Soaking will not get all completely open. You must used compressed air to clean them out after using carb cleaner
5. Have you bypassed the Oil pressure switch? A Defective pressure switch will also cause your type problem. Just ground it and see if it stays running. Doug
