i have the thunderbolt 7.5 motor i have completly went through and rebuilt everything that was bad. including carborator the motor did sit for a wile after the carb was done but it still ran fine for a little wile when i pulled it out this year. it ran good for about a weekend then started flooding out. it will run for about 30 seconds then die. the float is not stuck and i have ajusted the needle vaule mutiple times. anyother sujestions? or maybe if anybody has a good carb they might sell me?
