If it’s no smoking during operation, I would replace that gasket between the carb and filter cover and the if no more drips I would not worry about it. The OP has not said the the oil level increases, just that it is above the high mark. If it continues to drip or starts smoking, then it would be time to hit the repair shop. To be honest, but I’m not there and from the OP’s description, I don’t see anything which would be covered by warranty. The OP can do as he pleases and what works best for him. He asked for help and I’m not going to get in an argument over a line on a dipstick.
