Does anyone know if an ignition coil going bad make my sled sputter at 3/4 to full throttle but not at idle and not at 1/4 throttle?

does your sled sputter when on the top end, or does it bogg down and die? when it sputters that means your mixture is rich, when it boggs it means the mixture is lean. check your settings on your carbs, and make sure the choke plunger moves freely and is adjusted properly.
