Flynn's shop, Chad Flynn, Alexander, Il (217) 478-3811https://www.facebook.com/pages/Flynns-Shop/399871370115487He fixed up our 7.3 that had loss of power. Runs like a champ now. He normally fixes them and then drives it for a few days to make sure they run alright. Last time I was there he had about 6 or 8 trucks apart.
