Question
I have a 19.5 B&S Twin Turbo tractor. I start it and it runs good but it dies about an hour later and I have to waite from 30 to 60 min's to re start it then it dies againe sooner.
I have cleaned the carb., no help, then replaced the coil. It ran great the first time I used it after the coil then it dies (2ed.)the next time.
Can you tell me what to do next to got this running??
